Overview: Types of Bonds (Q4) Overview: Types of Bonds (Q4) There are 2 bond types : ionic and covalent In ionic bonding one atom has a stronger attraction for electrons than the other, and “steals” an electron from a second atom In covalent bonding the attraction for electrons is similar for two atoms. They share their electrons to obtain an octet. Read “types of bonds” on handout. Do Q4. MgO (ionic), CaCl
