|Type of Bond||How is the bond formed||Characteristics||Example|
|Ionic||Electrical attraction of cations and anion||Electrons transferred between atoms||Sodium-Chloride(NaCl)|
|Covalent||Sharing of Electron Pairs between two atoms||Sharing of Electron Pairs between two atoms||Hydrogen Chloride(HCl)|
There are two types of Covalent Bonds: polar and nonpolar covalent Bonds. A nonpolar-covalent bond is a covalent bond in which the bonding electrons are shared equally by the bonded atoms, resulting in a balanced distribution of electrical charge. A polar-covalent bond is a covalent bond in which there is an unbalanced distribution of electrical charge. An example of a nonpolar-covalent bond is Hydrogen Gas(H2). An example of a polar-covalent bond is Water(H2O).
