Ionic Bonds Molecular Cations and Anions Molecules can also lose or gain electrons to become cations or anions. For example,  the  NO 3  molecule will gain an electron to form the nitrate anion. If you count up all of the electrons you'll find that all of the atoms feel like neon. Here is the ammonium ion, an example of a molecular cation. The ammonium ion has given up an electron to become a cation. Molecular Cations and Anions:  Ionic Bonds

Ionic bonds  are generally formed when you bring atoms which really want to lose electrons  together with atoms which really want to gain electrons. The  Na +  cation and the  Cl -  anion are held together by  electrostatic or ionic bonds . There  is no sharing in ionic bonding. The anion takes the electron for itself and the cation is happy
