The Arsenic in AsH3 typically has a plus one charge. Therefore the H must have a -1 charge to create the compound.
The oxidation number of hydrogen is almost always 1 and should be so in AsH3.
AsH3 is Arsenic hydride.
AsH3 is a polar molecule because it is asymmetrical.
NH3 is more polar than AsH3, this is the same as comparing H2O and H2S.

Hydrogen always has a charge of + or - 1 ... for instance look at H20 ... H2 = +2 when O = -2.
Charge of a H is +1.There are three H atoms.
Arsenic trihydride
helium`s charge is H+, is a positive charge
The Ionic charge of H2O is 0 because H has a +1 charge and there are two H so it equals +2 and O has a -2 charge. So they balance out to a charge of zero
