Intramolecular Forces – ionic, covalent

Question 1

Ionic Bonds:

Answer 1

Ions are atoms that have lost or gained electrons.
Anion: Negatively charged ion (gains electrons).
Cation: Positively charged ion (loses electrons).
Ionic bonds form between oppositely charged ions and dissolve in water.

Question 2

Covalent Bonds:

Answer 2

Form when atoms share pairs of valence electrons.
For example, in Molecular Hydrogen H2, both hydrogen atoms share their electron to fill their valence shells.
