Question

the molecule having an atomicity of 4 is :​

Answer 1

Answer:  NH3 (ammonia) has a atomicity of four.

Explanation:  Atomicity is defined as the number of atoms that are present in the molecule of the compound.

To find atomicity of a given compound , we count the total number of atoms in it.

NH3 (ammonia) is made up of 1 atom of nitrogen and 3 atoms of hydrogen.Thus, the atomicity is 4.

Answer 2

The molecule having an atomicity of 4 is a Phosphorus molecule.

• The given question is incomplete and the options are not given. The options should have been:

         A. Sulphur molecule

         B. Ozone molecule

         C. Phosphorus molecule

         D. Methane molecule

• Molecules have the property of atomicity.
• Molecules are created when a group of atoms joins together through a chemical connection.
• The atomicity of a molecule is determined by the number of atoms that make it up.
• The sulfur molecule is made of 8 atoms of sulfur. Atomicity= 8
• The ozone molecule is made of 3 atoms of oxygen. Atomicity = 3
• Phosphorus molecule is made of 4 atoms of phosphorus. Atomicity = 4
• A methane molecule is made by the bonding between 1 carbon and 4 hydrogen atoms. Atomicity = 5
• Hence, phosphorus molecule is the correct answer having atomicity 4.
