Explain the formation of covalent bonds in nitrogen molecule (N_(2)).

Answer»

SOLUTION :The atomic NUMBER of nitrogen is 7, so its electronic configuration is `{:(K,L),(2,5):}`.
Thus, nitrogen has five electrons in its L shell.
Therefore, it needs three more electrons to fill the L shell.
Two ATOMS of nitrogen share three electrons of L shell to form a MOLECULE of nitrogen `(N_(2))`.
As a RESULT, each atom of nitrogen attains the electronic configuration of their nearest noble gas neon (Ne), which has eight electrons in their L shell
These six valence electrons are depicted by dots or crosses is shown as follows:
