Question

What is a atomicity of Aluminium Nitrite.

Answer 1

The elements present in the molecules are Aluminium, Sulphur and Oxygen. In this molecule, 2 atoms of Al, 3 atoms of sulfur and 12 (4×3) atoms of oxygen are present.

Thus the

atomicity of the molecule is 17 (2+3+12).

Since the aluminum ion has a charge of 3+, and the nitrite ion has a charge of 1-, there need to be three nitrite ions for every aluminum ion. Therefore, the chemical formula for aluminum nitrite is Al(NO2)3 .

Answer 2

Answer:

atomic no is 13

valence electrons are 3
