Answer: due to bond pair - lone pair and lone pair -lone pair repulsion
Explanation:
In , nitrogen is the central atom and there are 3 Hydrogens as monovalent atoms. The number of electron pairs is 4 that means the hybridization will be
and geometry of the molecule will be pyramidal as there are three bond pairs and one lone pair.The bond angle for pyramidal geometry is 107°. The bond angle reduces due to lone pair bond pair repulsions.
In , oxygen is the central atom and there are 2 Hydrogens as monovalent atoms.
The number of electron pairs is 4 that means the hybridization will be
and geometry of the molecule will be bent as there are two bond pairs and two lone pairs.The bond angle for pyramidal geometry is 104.5°.The bond angle reduces further due to greater lone pair-lone pair repulsions.

Answer:
Three hydrogen atoms to form PH₃.
Explanation:
Hello!
In this case, since the elements belonging to the nitrogen family (N, P, As, Sb and Bi) show five valence electrons, because there are five electrons at their outer shell, it is clear that if phosphorous bonds with hydrogen, it is going to require the same amount of oxygen atoms (3) because elements having five valence electrons need 3 bonds in order to attain the octet (5+3=8).
Therefore the compound would be:
Which is phosphine.
