NH2-, NH3, and NH4+ have H-N-H bond angles of 105, 107 and 109.

thus angle between 2 election pair is greater thn 1 electron 1 bond thn 2 bond..

so.. if angle between electron pair is greater so.. it makes the angle between H - N-H bond
smaller
thus.. similarly.. it can be said that
the bond angle between H-N-H in NH2- is less than NH3 than NH4 +
NH2- has electron pair - electron pair repulsion
NH3 has electron pair - bond pair repulsion
NH4+ has bond pair - bond pair repulsion
