Be vs Cl

[Karina Rodriguez 2H]

Beryllium is higher on the periodic table than chlorine, but chlorine is farther right than Be, how do I remember which has higher electronegativity?

[Mackenzie Van Val 3E]

Hi Karina! I look at this when looking at electronegativity: Cl is much further right on the periodic table than Be, but Be is only one row higher than Cl. Therefore, it makes sense that Cl has a higher electronegativity than Be. Hope this helps!

[dana hu 1B]

Cl is more electronegative because it is further to the right and up on the periodic table.

[Kyle_Lee_2B]

Though Be is higher than Cl in the periodic table, the number of spaces from left to right far outway the number of spaces up and down the periodic table. Thus Be has a lower electronegativity than Cl.

[Agustina Santa Cruz 2F]

Be is higher in electronegativity because the periodic trend for increasing electronegativity is going right and up.

[Yun Su Choi 3G]

Electronegativity is the tendency to gain an electron. Since Cl has 7 valence electrons, it is more likely to attract an electron to fulfill an octet whereas Be has 2 electrons and is more likely to lose electrons to be more stable.

[Bai Rong Lin 2K]

Beryllium is higher on the periodic table than chlorine, but chlorine is farther right than Be, how do I remember which has higher electronegativity?

This is because Cl is further right, which would allow it to have more electronegativity considering that Be is only one row higher than CL

[Hasan Mirza 3F]

As a general rule, you can determine which is more electronegative based on the atoms' proximity to the top right corner. In this case, Cl is much closer to the top right and is much more electronegative.

[Jay Solanki 3A]

Another way to compare electronegativities is to compare its placement to fluorine, the most electronegative atom. Since chlorine is closer to fluorine on the periodic table than beryllium, chlorine is more electronegative. Hope this helps!

[Jacob Schwarz-Discussion 3I]

Hey Karina!!
Although Be is one row higher than Cl, Cl is much farther to the right than Be. Because it is much farther to the right, this outweighs the fact that Be is one row higher. Cl therefore has the higher electronegativity.

[Charlotte Adams 1A]

The elements closest to Fluorine have a higher electronegativity.

[DPatel_2L]

Cl because it is furthest to the right nearest to fluorine

[CesarLec1]

remember that going across a period, electronegativity increases but going down a group it decreases, Since Cl is more to the right its electronegativity is higher.

[Hailey Kang 2K]

Hi! Electronegativity increases up and to the right. Therefore, Cl will be higher. Also, electronegativity refers to the atom's tendency to attract electrons. Since Cl has 7 valence electrons, it really wants to attract one to complete its octet. This means electronegativity will be higher.

[Neha Jonnalagadda 2D]

A good way to remember it is that Cl is one of the most electronegative elements on the periodic table and also it is much farther right on the table than Be. Therefore, it is way more electronegative.

[Ananya Sridharan]

I think that Cl has a higher electronegativity because it is farther up and to the right on the periodic table. You can also say that it is closer to Fluorine.

[Acharya Ranawat 3E]

While Be is further up, Chlorine is much farther to the right. Also, chlorine has 7 valence electrons meaning that it is much more likely to hold an electron closer to it. Hence, chlorine has a higher electro negativity, hope this helps!

[Lindsey Walter 3E]

Chlorine is going to be far more electronegative than Beryllium. I like to remember electronegativity by imagining an arrow pointing from Francium to Flourine, demonstrating the extremes of electronegativity and the trend. Chlorine is way closer to one extreme, Flourine than Beryllium, so it's more electronegative.

[Ashwin Vasudevan 3A]

Further right is more electronegative. You can see that Cl is very close to Fluorine which is the most electronegative element.

[michaelcrisera]

Although Be is above Cl on the periodic table, Cl is farther right. Electronegativity is a measure of an element's ability to attract an electron, so Cl will have a higher electronegativity than Be because it has 7 valence electrons, so it is very eager to gain another electron.

[Rachel Bartley 2B]

Chlorine is going to be more electronegative than Berilium because it is further right on the periodic table, which indicates more electronegativity than if you were to look at elements above and below each other.

[BriannaDis2C]

Higher electronegativity is based on the atoms' proximity to the top right corner of the periodic table. Cl is much closer to the top right and is much more electronegative than Be. When looking at a periodic table remember:

————> strongest
^
|
weakest |

[Zechuan Rao 1K]

What I like to do is familiar myself with the most electronegative and common atoms. So F is the most electronegative, than Oxygen, then Cl, then N.
What you can imagine a line pass through Cl and the space between N and O. This will give you insight on the general trends of electronegativity.

[Chance Lee 1G]

Be would be less electronegative compared to Cl atoms. This is because Cl atoms are the second most electronegative atom behind Fluorine. Be, on the other hand, is nearer to the other side where electronegativity are much less, therefore, Cl would be more electronegative than Be.

[Kaitlyn_Urquilla_1I]

Hi! Since the more electronegative elements are to the top right of the periodic table, Cl would be more electronegative than Be.

[Saebean Yi 3E]

The trend in electronegativity in the periodic table is that it increases as it goes from left to right, and increases as it goes down to up. Remember, Cl has 7 valence electrons, so it is more likely to attract shared electrons to fill the octet, opposed to Be, which only has 2 valence electrons.

[Zara Okeiyi 3C]

Chlorine is much further to the right on the periodic table than beryllium, however beryllium is only one row higher than chlorine. Therefore, it makes sense that chlorine is more electronegative.

[Shania Garrison Discussion 3E]

I think it might be helpful to look at a chart with electronegativity values to kind of get a feel for the trend. He said we don't need to memorize it, but it might still be help it to see it a few times and analyze the patterns.

[Madelyn_Rios_2c]

Cl is more electronegative than Be because it is further to the right on the periodic table because it has seven valence electrons which makes it more electronegative since it is more likely to attract another electron in order to become stable.

[madeleinewright]

Chlorine is more electronegative because it is much further to the right than beryllium, whereas beryllium is only one row higher than chlorine.

[azurexrose]

Cl is closer to fluorine, the most electronegative element, than Be, so Cl is more electronegative.

[Nishan Reddy 3K]

Be is a metal and most metals in the s block have very low electronegativities since they want to give up their electrons, not pull another atom's one. Thus, metals almost always have an electronegativity smaller than a nonmetal. The general trend also is that electronegativity increases as you go up and to the right of the periodic table.

[Hailey Sarmiento 3E]

Be is on the far right side in the alkaline metals and all metals tend to lose electrons rather than gain electrons like the nonmetals on the far right side where Cl is. I tend to mark F as being the most electronegative and whatever is closer to F is probably more electronegative

[505771920]

It can be helpful to remember F as the most electronegative and base the other elements off of that

[Ana Luiza S]

When I think of electronegativity, I tend to just remember fluorine as the most electronegative element and then base other elements' electronegativity depending on their proximity to fluorine. So nitrogen, oxygen and chlorine are all very close to fluorine on the periodic table, meaning they are probably very electronegative. This doesn't apply to noble gases though.

[Kelly_Luong_1F]

Cl would be more electronegative because it is closer to F, the most electronegative element.

[Tyler Olson 1E]

Because Cl is much further to the right, it has a higher electronegativity shown through the periodic trend.

[Denise Chavez 2G]

Electronegativity in the periodic table increase from left to right and down to up, so since Cl is farther to the right than Be it is more electronegative than Be.

[Akshat Katoch 2K]

An atom is more electronegative as you go to the top right. So for Be vs Cl, Cl is much closer to the top right compared to Be and thus is far more electronegative than Be.

[Amy Jordan 2A]

Cl is more electronegative because the periodic trend for electronegativity is that it increases up and to the right, with F being the most electronegative. Thus, you can think of it as the element closest to F is the most electronegative.

[205819952]

Because it is more to the right and higher on the periodic table, Cl is more electronegative.

[Parinita Jithendra 2A]

I would say look the periodic table diagonally because it helps see which is closest to the top right would be more electronegative. In this case, Cl would be more

[Justin An 2L]

A good way to remember electronegativity is to think about regions/periodic trends; for electronegativity, it increases as you move to the up and right of the periodic table!

[Julia Zahra]

Cl is much further right so it is more electronegative

[905701360]

Cl is more electronegative because it is further to the right and higher up on the periodic table.

[605778346]

Chlorine has a higher electronegativity. It is farther right to the periodic table

[Jessica Ghiuzelian 1H]

Electronegativity increases up a period and towards the right of a group. So since Cl more to the right on the periodic table, it would have a higher electronegativity.

[Vashe Sundar 3H]

Cl is more electronegative because it's farther to the right. A good rule of thumb is that the closer an element is to F (the most electronegative element), the more electronegative it becomes.

[Claudia Longo 2J]

Beryllium is higher on the periodic table than chlorine, but chlorine is farther right than Be, how do I remember which has higher electronegativity?

Chlorine is significantly further right along the periodic table than Beryllium is high on the periodic table.

[Arpita Padhy 3E]

Even though Be is further up than chlorine on the periodic table, chlorine is a lot further to the right which makes it more electronegative.
