Question

define atomicity and valency. Write atomicity and valency of 1 oxygen 2 sodium 3 phosphorus​

Answer 1

Answer:

Atomicity is defined as the total number of atoms present in a molecule. For example, each molecule of oxygen (O2) is composed of two oxygen atoms. So atomicity of oxygen is 2.[1]In older contexts, the term atomicity is sometimes used in the same sense as valency.

Answer 2

Answer:

• Atomicity is defined as the total number of atoms present in a molecule. For example, each molecule of oxygen is composed of two oxygen atoms. So atomicity of oxygen is 2.

• In chemistry, the valency of an element is the measure of its combining capacity with other atoms when it forms chemical compounds or molecules.

• The valency of oxygen is 2, sodium is 1 and phosphorus is 3/5.
