
2.
Why do atoms combine to form compounds?

3.
4.
Atoms combine to form compounds for stability. Atoms in compounds have
octets (or duets) as a result of their bonding.
What is a diatomic element? List all 7 diatomic elements.

A diatomic element is one that bonds with itself when no other atom is
available. They do not exist as solo elements.

Br2, I2, N2, Cl2, H2, O2, F2 (BrINClHOF)
