Bonding

Bonding

Atoms bond to gain stability.

Bell work: Answer the Questions

• How do atoms gain stability?

• How many electrons can the first energy level hold?

• How many electrons can the second and third energy levels hold?

Types of bonding

COVALENT BONDING - Electrons are shared between atoms of two nonmetals.

IONIC BONDING - Electrons are transferred between a metal and a nonmetal.
