: [tex] \implies[/tex] A molecule with 3 atoms is called tri- atomic Tri-atomic gases are gases with 3 atoms per molecule.
Examples of Tri-atomic gases are :
The Ozone - O3 ( 3 atoms of oxygen)
The Carbon di-oxide - CO2 ( 1 atom of carbon and 2 atoms of Oxygen)
The Nitrous Oxide - N2O (2 atoms of Nitrogen and 1 atom of Oxygen)
The Sulfur dioxide - SO2 ( 1 atom of sulfur and 2 atoms of oxygen)
Triatomic Liquid:
The Water - H2O ( 2 atoms of hydrogen and 1 atom of oxygen)

The Diatomic molecule means the molecule contains two atoms in their composition and triatomic means the molecule contains three atoms in their composition. The three atoms should be the same or different.
The triatomic molecule should have three atoms and it is not mandatory to have all three same atoms.
The shape of the triatomic molecules is going to depend on the number of lone pairs of electrons present in the structure of the molecule.
For example water is a triatomic molecule containing two hydrogen atoms and one oxygen in its composition. The oxygen has two lone pairs of electrons, making the structure of the molecule as bent with a dipole moment of 1.85D.
Coming to the structure of carbon dioxide. Carbon dioxide contains three atoms, one carbon and two oxygen atoms with a linear structure and has zero dipole moment.
The number of atoms in a molecule is called atomicity. The atomicity of triatomic molecules is three due to the presence of three atoms.
The atomicity of diatomic molecules like hydrogen and nitrogen is two due to the presence of two atoms.
The Tri means three. Therefore triatomic molecules contain three atoms.
Triatomic molecules are molecules composed of three atoms, of either the same or different chemical elements. Example: Ozone(O3) is a triatomic molecule because ozone contains three oxygen atoms. Water(H2O) is an example of a triatomic molecule that consists of two hydrogens and one oxygen atom.
