Question
Using electron-dot diagrams which show only the outermost shell electrons, show how a molecule of nitrogen, N2, is formed from two nitrogen atoms. What name is given to this type of bonding? (Atomic number of nitrogen is 7)

Solution
The atomic number of nitrogen is 7. Its electronic configuration is 2, 5. Hence, it contains five electrons in its outermost shell.
Three electrons from each nitrogen atom are shared to complete its octet. This sharing of electrons results in covalent bonding in a nitrogen molecule.
