scaled up models
Why do scientists use different types of models to represent compounds?
Atom is the word used to describe a single unit of an element by all professional scientists. That is the only word you should use.
because they are to small for anyone to study.
Scientists use symbols to represent elements and compounds. The symbols of a chemical element are abbreviations that are used to denote a chemical element. Typically, they are one or two-letters long with the first letter (only) capitalised; temporary names are three-letters long. !
Symbols are universally understood across many languages. Also, using symbols rather than full names helps scientists to avoid the repetition of writing the long names of elements and atoms again and again.

Why do scientists use different types of models to represent compounds?
scientist use models to show or explain easier
why scientists use models to represent earths process
the symbol scientists use to represent the atomic mass number is the letter U.
Hologams to represent the Earth would be too expensive.
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.
