Question

Define atomicity. Atomicity of the element ozone and chlorine

Answer 1

$\large \bold{ATOMICITY}$

The number of atoms present in one molecule of that element is known as its atomicity.

We know

Oxygen and chlorine are diatomic so, they have 2 atomicity.

Or we can do this by calculating,

FOR OXYGEN :--

▶Gram molecular weight of oxygen = 32 g

▶Atomic weight of oxygen = 16 g

$\boxed{ATOMICITY = \dfrac{Gram \: molecular \: weight }{Atomic \: weight}}$

$\mathsf{ATOMICITY = \dfrac{32 }{16}}$

$\boxed{ATOMICITY = 2}$

FOR CHLORINE

▶Gram molecular weight of chlorine = 71 g

▶Atomic weight of oxygen = 35.5 g

$\boxed{ATOMICITY = \dfrac{Gram \: molecular \: weight }{Atomic \: weight}}$

$\mathsf{ATOMICITY = \dfrac{71 }{35.5}}$

$\boxed{ATOMICITY = 2}$

Answer 2

• The number of atoms present in one molecule of that element is known as its atomicity.
