Answer 1

Answer:

Diatomic gases are gases composed of only two atoms,

Triatomic Gas - Molecules consist of 3 atoms

Polyatomic gas - Molecules consist of 4 or more atoms.

Answer 2

Answer:

DIATOMIC GAS

Diatomic molecules are molecules composed of only two atoms, of the same or different chemical elements. The prefix di- is of Greek origin, meaning "two". If a diatomic molecule consists of two atoms of the same element, such as hydrogen (H2) or oxygen (O2), then it is said to be homonuclear.

TRIATOMIC GAS

Triatomic gases: Molecules of these gases have three atoms and are called triatomic having atomicity equal to three. Some common example of triatomic gases is carbon dioxide, water vapour, nitrous oxide, ozone etc.

POLYATOMIC GAS

pertaining to a molecule containing more than two atoms
