Hydrogen forms only one bond, valency of hydrogen is-
1
-1
7
2
Hydrogen outer most orbit has one electron and has the capability of combining with electron of other element.
If the valency of hydrogen is 1 and and the valency of carbonate is 2 then how HCO3 is formed?
Valency of hydrogen is 1 and that of sulphur is 2. What should be the formula of hydrogen sulphide?
