Question

The atomicity of K2Cr2O7 (potassium dichromate) is _______________.

a) 9 b) 11 c) 10 d) 12​

Answer 1

Explanation:

The number of atoms in the molecules of an element is known as its atomicity. In case of k2Cr2O7, there are 2 atoms of potassium(K), atoms of chromium(Cr) and 7 atoms of oxygen (O). So the atomicity of this compound is the sum of all the atoms present in this compound. So the atomicity of k2Cr2O7 is 11

hiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii
