Plz answer correctly.. I need it ASAP

If all the particles in a material are made up of

several smaller particles, and every larger particle

is identical, is the material a pure substance or

not? Explain your reasoning.

A pure substance is something like a compound and element. This material made of several particles which seem to be two different particles, I believe, is a mixture. So, it is not a pure substance mixtures are made up of more than one particle while compounds (In a fixed ratio, the fusion of two or more than two atoms) and elements are made up of one molecule essentially.
