this molecule has a similar shape to ammonia, however the bond angles are less- ammonia is 1070 whereas arsine is only 91 0. Usually it is said that the hybridisation in AsH3 is sp3 (however this would imply a bond angle of 109.5- which is close to the ammonia angle)- however the angle of 91 0 is so close to the angle between the p orbitals (900)that it suggest there is no hybridisation at all, and that the As- H bonds involve only p orbitals.
ap3
AsH3 is Arsenic hydride.
AsH3 is a polar molecule because it is asymmetrical.
The oxidation number of hydrogen is almost always 1 and should be so in AsH3.
NH3 is more polar than AsH3, this is the same as comparing H2O and H2S.

arsenic trihydride
PF5
The Arsenic in AsH3 typically has a plus one charge. Therefore the H must have a -1 charge to create the compound.

The hybridization of PH3 is sp3
The hybridization is sp3d.
