Trend of Electronegativity

Postby chrisavalos-2L » Sat Dec 01, 2018 8:29 pm

I was wondering what the trend for electronegativity was, is it the same as ionization energy?

Yes they have similar trends. Both increase as you move right across a period and up a group/family.

Yes. The electronegativity trend is that it increases as it goes up and to the right on a periodic table.

The trends are the same. They increase up a group and across a period. It usually helps me to draw a diagonal line up and across the periodic table to remind myself of this trend during tests!

Electronegativity increases across a period and up a group, so it is the same trend as ionization energy.

Yes, the trend for electronegativity is the same as the trend for ionization energy.

Electronegativity increases as you go up the periodic table and as you go across the periodic table. Same goes for ionization energy.

Electronegativity increases as you go up the periodic table as the energy level is lower so electrons are held closer to the nucleus with lower atomic radii and an increased effective nuclear charge. As you go across the periodic table electronegativity also increases as the energy level remains the same but atoms increase in atomic number and the increased number of protons also increases effective nuclear charge pulling electrons tighter increasing electronegativity. As effective nuclear charge increases so does electronegativity.

Electronegativity increases across a period and decreases down a group.

it is a little bit different, it increases when it goes up. F has a large electronegativity.

The general trend for electronegativity is that it increases across a period and decreases down a group. I think of it as being at its highest at the top right, and at its lowest at the top left. Fluorine (F) is the most electronegative element.

Yes they do, goes right across a period and up a group on the periodic table.

In discussion someone mentioned a noble gas rule/shortcut when we were discussing periodic table trends? Does this relate to electronegativity? If not, can someone explain what it is?

An easy way to remember the trend of electronegativity is to think about the concept of electronegativity. Electronegativity is the tendency to grab electrons. The atoms on the right side of the periodic table want to grab electrons to reach octet. Therefore, the electronegativity increases as you move to the right side of the periodic table. Electronegativity decreases as you move down the table because there’s electron shielding effect.

yes they are pretty much the same thing with different meanings. Right and up increases.

Yes both electronegativity and ionization energy increase as you go up the periodic table and down the period.

I remember my TA mentioning that it is okay to view them as having the same trends.

the trends are identical (: both electronegativity and ionization energy increase as you go up the periodic table and increase also as you go right on the periodic table.
