Back

Electronegativity decreases down a group.

Front

Define valence electrons.

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds.

Front

What is the significance of the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.
