A scientist while working with different elements in his lab, found that element ‘X’ forms a compound ‘H2X’ with Hydrogen, and element ‘Y’ forms a compound ‘HY’ with Hydrogen. (3) a) Deduce the valency of elements ‘X’ and ‘Y’ based on the scientist's findings. b) On further investigation, he found another compound ‘HY3’ formed by element ‘Y’. What, in your opinion, does this suggest about the valency of element ‘Y’?
