Question

What is the valency of chromium ?​

Answer 1

Explanation:

Thus, one atom of the metal combines with two chlorine atoms to form the dihalide (CrCl2), and with three chlorine atoms the trihalide (CrCl3). Hence, the valencies of chromium can be taken as 2 and 3, as in the case of iron, which is also a transition metal.
