Question

ASSERTION (A): Atomicity of ozone is three while that of oxygen is two.
REASON(R): Atomicity is the number of atoms constituting a molecule.

Answer 1

Answer:

Assertion is False and Reason is True. Atomicity : The number of atoms present in a molecule is defined as the atomicity. Hence , Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

Explanation:

Atomicity refers to the number of atoms present in one molecule of an element, substance or compound. This can also be considered the nature of molecules. Depending on the atomicity of the substance, it can be mono, di, tri or poly atomic

For example, oxygen orFor example Neon (Ne), Helium (He), Argon (Ar) etc.

Atomicity is a term that is associated with molecules. It is sometimes referred to as valence.

Atomicity can be defined as the total number of atoms that are present in a molecule of an element. Molecules of different elements have different numbers of atoms in them. Atomicity of molecules can be divided into different groups:

(1). Monatomic Molecules: Molecules that consist of 1 atom are known as monatomic molecules. All noble gases are monatomic.

(2). Diatomic Molecules: Molecules that consist of two atoms are known as diatomic molecules. The gases that are the main components of the atmosphere are diatomic.

Answer 2

Final answer:

Assertion (A): Atomicity of ozone is three while that of oxygen is two. Reason (R): Atomicity is the number of atoms constituting a molecule.

Both assertion (A) and its reason (R) are correct.

Given that: We are given,

Assertion (A): Atomicity of ozone is three while that of oxygen is two.

Reason (R): Atomicity is the number of atoms constituting a molecule.

To find: We have to find the given assertion (A) and its reason (R) is correct or not.

Explanation:

• Given, assertion (A): Atomicity of ozone is three while that of oxygen is two. Its reason (R): Atomicity is the number of atoms constituting a molecule.

Both are correct.

• Atomicity can be defined as the total number of atoms that present in a single molecule of a substance or compound.
• According to atomicity of a substance, we can identify whether the substance is mono, di, tri or poly atomic.
• Molecule of oxygen has a chemical formula $O_{2}$ is composed of two oxygen atoms.

So atomicity of oxygen molecule is 2 and is diatomic molecule.

• Chemical formula  of ozone is $O_{3}$ which means it composed 3 atoms of oxygen, so atomicity of ozone is 3 and is triatomic molecule.

Hence, assertion (A) and its reason (R) are correct.
