Ionic bonds occur when the charges of the electrons attract one another to form a neutral molecule. Ionic bonds are most commonly found in salts, and they form a very powerful bond, although it can be broken by water. Covalent bonds occur when atoms share electrons. Atoms have an outer shell consisting of a certain number of electrons.

Chlorine having valence electrons in the 3rd energy level, will also have access to the 3d sublevel, thus allowing for more than 8 electrons. Elements in the first 2 periods of the Periodic Table do not have access to the d sublevel and must adhere to the octet (or duet H and He) rule . If we were to leave the solid out in the air, it would soon decompose to a white solid due to either carbon dioxide or water vapor in the air. Potassium superoxide is paramagnetic. The simple explanation is that with a formula of O 2 -2 , there are simply an odd number of electrons in the anion (6 e - + 6 e - + 1 e - = 13 e - ), hence it is ...

unpaired electrons are present in the Zn2+ and Co2+ ions. Zn2+, 3d10 ↑↓ Co2+, 3d7 ↑↓ Zn2+ has 0 unpaired d electrons, Co2+ has 3 unpaired d electrons. Co2+ is therefore paramagnetic and will be attracted by a magnetic field. Suggest why it is useful to replace Zn2+ with Co2+ when studying the nature of the active site in carbonic anhydrase.
The reason that it is paramagnetic is because the oxygen molecule has two unpaired electrons. Electrons not only go around the atom in their orbitals, they also spin, which creates a magnetic field. Unpaired electrons spin in the same direction as each other, which increases the magnetic field effect.
