Answer 1

Answer:

atomicity is the total number of atoms present in one molecule of a substance. All metals and some other elements, such as carbon, do not have a simple structure but consist of a very large and indefinite number of atoms bonded together. Their atomicity cannot be determined and is usually considered as 1.

Atomicity may vary in different allotropes of the same element.

1. each molecule of oxygen (O2) is composed of two oxygen atoms. So atomicity of oxygen is 2

2.The atomicity of nitrogen is 2 in N2 molecules, as this molecule contains 2 atoms of nitrogen element.

3.Number of atoms in one molecule of sulphur = 8 (because sulfur exists as S8 ). Therefore, the atomicity of sulfur is 8.

4.The Atomicity Of Argon is monoatomic.

Answer 2

The atomicity of the following elements is given below.

Explanation:

• Atomicity is the number of atoms of any element in which it is generally present in nature.

• The type of atomicities are monoatomic (one), diatomic (two), triatomic (three) and polyatomic (four or more than four).
• Let's discuss the atomicities of these elements:

i) Oxygen: It is present as diatomic ($O_{2}$) in the atmosphere as a gas, and also as triatomic ($O_{3}$) in the stratosphere layer as Ozone gas.

ii) Nitrogen: It is present as diatomic ($N_{2}$) in the atmosphere as the most abundant gas.

iii) Sulphur: It is present as a polyatomic ($S_{8}$) in a ring structure and exists as a solid.

iv) Argon: It is present as monoatomic (Ar) in the atmosphere as a noble gas.
