Bonding and Electronegativity
There are three main types of bonds , Ionic, Covalent, and Mettalic bonds. Ionic bonds are bonds between metals and non-metals. Covalent bonds are bonds between non-metals. Metallic bonds are bonds between pure metals.
Electronegativity
Electronegativity (en) is a measure of an atom's attraction for electrons in a bond. Atoms with greater en attract more e⁻. Polar covalent bonds form from an unequal sharing of e⁻. Non-polar covalent bonds form from an equal sharing or e⁻.
Bonds
The type of bond formed can be predicted by looking at the difference in electronegativity (en) of the elements.
