Question

An element X shows two valencies of 2 and 3. What is the formula of two chlorides of this element?

Answer 1

Answer:

XCl2, (XCl2)3

may be this is the what you want to get

Answer 2

Knowing that the valenecy of oxygen is 2, we can write down the formulate of the two oxides of element X as follows : (a) Formula of oxide of element X when its valenecy is 3. Thus, the formula of oxide of elemene X when its valency is 3 is X2O3. Thus, the formula of oxide of element X when its valency is 5 is X2O5.
