27Types of Bonds
A. Electronegativity - The ability of an atom to
attract electrons to itself in a bond
1. Periodic Trends (link to size)
Metals – Low Electronegativity
Non- Metals – High Electroneg
The smaller the atom, the higher the
electronegativity
Types of Bonds
a. Molecular Compounds (non-metals)
• Sharing of electrons
• Covalent or polar covalent bonds
• Ex: H
2
b. Ionic Compounds (metal + non-metal)
• Exchange (stealing) of electrons
• Ex: NaCl
