Dear student..
Here are the valency of few non-metallic elements
Chloride = (-1)
Bromide = (-1)
Iodide = (-1)
Nitrate = (-1)
Hydroxide= (-1)
Bicarbonate = (1)
Bisulphite = (-1)
Bisulphate = (-1)
Aluminate = (-1)
Permagnate = (-1)
Sulphide = (-2)
Sulphite = (-2)
Sulphate = (-2)
Carbonate = (-2)
Dichromate = (-2)
Zincate = (2)
Phosphate = (-3)
Nitride = (-3)
Remaining are not clearly visible.
Hope it is clear
Regards
