Question

An element X forms a compound XH3 white hydrogen. Another element Y forms a compound YX2 with X. Given that the valency of hydrogen is 1, what are the ValenciaтАЩs of X and Y

Answer 1

Hi friend,

Answer:-
X = -3
Y = +6

Reasons:-

As the sign would be reversed in case of oxidation state.

Hydrogen must probably have (-1)

In case of YX2 we found that

X=-3

Then -3-3=-6

Hope I helped you a little!!!!
