Some or all of the outermost electrons participate in forming bonds to other atoms, these electrons are called the valence electrons. For example, in water, H2O, each of the two H atoms donates its only 1s electron to form a bond with the oxygen. The oxygen contributes its two unpaired 2p electrons (see the electron configuration of oxygen above). However as a group 2 element barium easily loses 2 electrons to form the +2 cation.

Because each alkali metal (M) has an ns 1 valence electron configuration, the M 2 molecule has two valence electrons that fill the σ ns bonding orbital. As a result, a bond order of 1 is predicted for all homonuclear diatomic species formed from the alkali metals (Li 2, Na 2, K 2, Rb 2, and Cs 2). The electrons in the p-orbital in N atom experience less repulsion, thus more stable and more ionization energy. Whereas in case of O atom the 4th p-electron atom can be removed more easily as it experiences more repulsion from the electrons in the p-orbitals already present. Hence nitrogen, Oxygen atom has less ionization energy than Nitrogen ...

(b) Detailed calculations indl cate that the value of S for a 3p electron in a sulfur aton is 10.52. The 3p electrons in phosphorus are all unpaired. In sulfur, two of the 3p electrons are paired. There is some repulsion between paired electrons in the same sub-shell, so the force of their attraction to the nucleus is reduced. This means that less energy is needed to remove one of these paired electrons than is needed to remove an unpaired ... Elemental iron and iron (III) are paramagnetic because of the necessity of unpaired electrons in their orbitals. Iron (II) is also in this same position most of the time. When iron (II) is bonded to certain ligands, however, the resulting compound may be diamagnetic because of the creation of a low-spin situation.Psiphon for iphone
