2. Covalent bonds form between non-metal atoms that SHARE
electrons. Doing so helps them achieve a stable outer electron
shell.
Covalent bonds are stronger than ionic bonds. Each atom
pulls at the others’ electrons.

4. Polar covalent bonds occur when the two atoms are different.
The atoms with more protons has a stronger pull on the
electrons, so that atoms becomes partially negative.
As a result, the atom with a weaker pull becomes partially
positive.

7. Naming Covalent Compounds
Prefix
• Mono- 1
• Di- 2
• Tri- 3
• Tetra- 4
• Penta- 5
• Hexa- 6
• Hepta- 7
• Octa- 8
• Nona- 9
• Deca- 10
• First element in the formula is named first
using prefix
• Second element follows using # prefix AND
suffix ‘-ide’
• Mono is not used for the first element
• Example
• N2O
– Dinitrogen Monoxide
• N2O5
– Dinitrogen Pentoxide
