Question

Give two examples of each of the following: (a) a diatomic molecule containing atoms of the same element, (b) a diatomic molecule containing atoms of different elements, (c) a polyatomic molecule containing atoms of the same element, (d) a polyatomic molecule containing atoms of different elements.

Answer 1

Step-by-step explanation:

a) O₂( oxygen gas containing oxygen atoms only)

b)HCl( hydrogen chloride containing hydrogen and chlorine atoms)

c) P₄( Phosphorus containing 4 atoms of phosphorus)

d) NH₃( ammonia containing one atom of nitrogen and three atoms of hydrogen)

Answer 2

For a: The examples are
`N_2\text{ and }O_2`

For b: The examples are
`NaCl\text{ and }HBr`

For c: The examples are
`P_4\text{ and }S_8`

For d: The examples are
`H_2SO_4\text{ and }NaHCO_3`

Step-by-step explanation:

Diatomic molecule is defined as the molecule which is formed by the combination of two atoms.

Polyatomic molecule is defined as the molecule which is formed by the combination of more than two atoms.

Element is defined as the chemical specie which is formed by the same kind of atoms.

For the given options:

• Option a:

The examples of diatomic molecules that contain atoms of the same element are
`N_2\text{ and }O_2`

• Option b:

The examples of diatomic molecules that contain atoms of different element are
`NaCl\text{ and }HBr`

• Option c:

The examples of polyatomic molecules that contain atoms of the same element are
`P_4\text{ and }S_8`

• Option d:

The examples of polyatomic molecules that contain atoms of different element are
`H_2SO_4\text{ and }NaHCO_3`

Hence, the examples are written above.
