Study Notes
Covalent Bonds
- Elements with high ionization energy cannot lose electrons and elements with low electron affinity cannot easily gain electrons.
- Chlorine (Cl) has seven electrons in its outermost energy level. It is more likely to gain electrons rather than lose them.
- When two chlorine atoms come close together, they share one electron from each atom to form a pair. This is called electron sharing.
- As a result, both chlorine atoms gain eight (8) electrons in their outermost energy shell.
Types of Covalent Bonds
- Single bond: One electron from each atom forms a pair.
- Double bond: Two electrons from each atom form two pairs.
- Triple bond: Three electrons from each atom form three pairs.
