What is an ionic bond?

Back

An ionic bond is a type of chemical bond that occurs when one atom transfers electrons to another atom, resulting in the formation of ions.

What charge do metals typically have when they form ions?

Back

+1 or +2.

Front

What charge are the elements in group 2 as ions?

Back

+2.

What is a valence electron?

Back

A valence electron is an electron that is found in the outermost shell of an atom and can participate in forming chemical bonds.

Front

How many valence electrons do most ions have, except for those with low atomic numbers?

Back

8.

If Na⁺ and O²⁻ combine, what compound do they form?

Back

Sodium Oxide, Na₂O.

Front

What is 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.
