There are $4$ $4$ such bonds in the ammonium ion, $N H_{4}^{+}$ $NH_4^+$

Explanation:

Neutral ammonia has $3$ $3$ $\times$ $xx$ $N - H$ $N-H$ bonds, and also has a nitrogen-centred lone pair. This lone pair can form a donative bond to hydrogen,for instance:

$N H_{3} (a q) + H_{2} O \to N H_{4}^{+} + H O^{-}$ $NH_3(aq) + H_2O rarr NH_4^+ + HO^-$ .

Quaternary ammonium salts, $N R_{4}^{+}$ $NR_4^+$ , are also known. In both instances, there are 6 electrons formally associated with the nitrogen centre rather than 7, and thus it bears a formal positive charge in the representation.
