Hint: In chemistry, orbital hybridization (or hybridization) is the idea of mixing atomic orbitals into new hybrid orbitals appropriate for the pairing of electrons to shape chemical bonds in valence bond hypothesis. For instance, in a carbon atom which structures four single bonds the valence-shell s orbital consolidates with three valence-shell p orbitals to shape four identical \[s{p^3}\] combinations which are orchestrated in a tetrahedral plan around the carbon to bond to four different atoms.

Complete answer:
Obviously, there are similarly \[4\] electron pairs conveyed around the nitrogen centre in ammonia:\[N{H_3}\] . \[s{p^3}\] hybridization would be the portrayal, and the gross structure (of electron sets) is that of a tetrahedron. Yet, we portray molecular geometry on the basis of actual atoms, so the structure of alkali is pyramidal.
Moreover for\[N{H_2}^ - \;\;\], the amide ion, the \[4\] electron sets are conveyed around nitrogen as a tetrahedron. Once more, we describe structure on the basis of \[N - H\] bonds as it were. The structure of the amide particle is in this manner much the same as that of water, that is bent on the grounds that there are likewise 2 lone pairs on the central oxygen/nitrogen atom.
There are officially \[4\] electron pairs dispersed around the nitrogen in the amide molecule; \[s{p^3}\] hybridization would be the depiction

Note:
Nitrogen has \[5\] outer electrons, in \[N{H_2}^ - \;\;\]​ it increases an extra electron. Of the \[6\] electrons, \[2\] are shared with \[2\] hydrogen atoms to form \[2\] sigma bonds, the leftover \[4\] electrons fill \[2\] orbitals with \[2\] isolated electron pairs, similarly to \[{H_2}O\].
