Electrons found on an atom's outermost shell.
100
What does chemical bonding depend on?
The valence electrons.
100
When does negative and positive ions form?
Negative and positive ions form when atoms gain or lose electrons.
100
what is a covalent bond?
a bond that shares electrons.

What is chemical bonding?
the combing of atoms to form molecules or ionic compounds.
