Question

give example of each
i)triatomic molecules
ii)octatomic molecules ​

Answer 1

Answer:

1)  H2O, CO2 (pictured) and HCN.

2) sulphur, S8,

Answer 2

the examples of triatomic molecules is HCN

and the example of octaatomic molecules is S8

Triatomic molecules are molecules composed of three atoms, of either the same or different chemical elements. Examples include H2O, CO2 and HCN.

Octa atomic species are those which are made up of eight atoms. For example, sulphur molecule is an octaatomic molecule made up of eight atoms of sulphur and is denoted by S8.
