Nitrogen molecule electron configuration

Indicate the position of nitrogen in Mendeleev s periodic table of the elements, the electron configuration and the size of its atom, and the oxidation states it exhibits. Write the electron configuration of a nitrogen molecule. What is the bond multiplicity in it ... 

Write down the electronic configurations for the ground states of the molecules water, carbon dioxide, formaldehyde, ethene, benzene, and the nitrogen dioxide radical. The occupied MO s shall be given using the full point group symmetry of the molecule. 

We meet a different type of bond when we consider the structure of a nitrogen molecule, N2. Suppose we follow the same procedure as before. First, we write the atomic configurations, as shown in (39). There is a single electron in each of the three 2p-orbitals on each atom. However, when we try to pair them and form three bonds, only one of the three orbitals on each atom can overlap end-to-end to form a cr-bond (Fig. 3.13). Two of the 2/ -orbitals on each atom (2px and 2pv) are perpendicular to the internuclear axis, and each one contains an unpaired electron (Fig. 3.14, top). When the remaining 2p-electrons pair, their orbitals can overlap only in a side-by-side arrangement. This overlap results in a ir-bondI, a bond in which the two electrons lie in two lobes, one on each side of the internuclear axis (Fig. 3.14, bottom). Although a ir-bond has electron density on each side of the internuclear axis, it is only one bond with the electron cloud in the form of two lobes, just as a p-orbital is one orbital with two lobes. In a molecule with two ir-bonds, such as N2, the electron densities in the two iT-bonds merge, and the two atoms appear to be surrounded by a cylinder of electron density (Fig. 3.15). 

In the case of the ill surfaces, the electronic configuration of A and B atoms can be represented as in Fig. 2. ft is believed that the B surface atoms retain their sp3 tetrahedral configuration and can be considered analogous to the nitrogen atom in the H N H molecule. On the other hand, the A H... 

Boron, carbon, and nitrogen. According to Fig. 5.12, the B, molecule would be predicted to have a single o bond and be diamagnetic. Experimentally the B2 mdecufe is found lo have two unpaired electrons. The C2 molecule would be predicted to have an electron configuration and be...
