Question

the atomicity of K2 cr2 O7____​

Answer 1

atomicity is the numbers of atom present in a molecule.In this molecule 2 atoms of potassium,2 atoms of Cr and 7 atoms of oxygen are present.so atomicity is 11.

Answer 2

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.

Hence,

Atomicity = 2+2+7

=11

So the atomicity of k2Cr2O7 is 11.
