Identifying Elements

[Julianna_flores3E]

Is there a specific reason why some elements are metals, nonmetals, or metalloids in the same group?

[Olivia Yang 3J]

Elements in each group have the same number of valence electrons in the outermost shell and share similar chemical properties.

[Natalie Do 3F]

Even though some may have different qualities associated with metals (conductivity, malleability, etc) they are similar in terms of how and what they bond to because they have the same number of valence electrons.

[Adrienne Yuh 2B]

They have similar chemical properties and are usually grouped near each other.

[rita_debbaneh2G]

Elements within the same group share the number of valence electrons in common which is vital to their characterizing considering its the valence electrons that participate in the reactions. This explains similarities in chemical properties.

Hello! This is because those elements which share similar chemical properties are naturally grouped together, it makes it easier to find and analyze these elements.

[Yun Su Choi 3G]

Groups 1 and 2 (s-block elements) are all metals because they are highly reactive due to higher likelihood of losing an electron (low electronegativity). This behavior contributes to the characteristics of metals, such as good conductor of electricity and the formation of cations.
On the other hand, elements toward the right of the periodic table are nonmetals as they tend to gain electrons to become anions.

[Logan Wiedemann 3J]

All the elements in a group are similar because they all share the same amount of valence electrons!

[Melissa Solis 1H]

I think the simplest explanation would be that they all have the same amount of valence electrons .

[Polo Morales 3C]

Elements in the same group have the same number of valence electrons, and thus tend to have similar properties.

[Arshaun Faraji 2H]

The group that an element is placed in has to do with the number of valence electrons. Elements in the same group may have vastly different sets of properties, allowing them to be categorized differently in terms of metals, metalloids, etc. but they all have the same number of valence electrons.

[Sonia Virk 2A]

the organization of the elements comes down to the atomic number which is also the number of electrons the atom has and therefore it is in order of valence electrons

[Arad_Badiee_2B]

When you look down a vertical column, also known as a group, you will see elements that all have the same number of valence electrons. Hence, they have similar properties, which is why they are grouped in this way.
