​

Answer 1

Answer:

An atom a fundamental piece of matter. ... Everything in the universe (except energy) is made of matter, and, so, everything in the universe is made of atoms. An atom itself is made up of three tiny kinds of particles called subatomic particles: protons, neutrons, and electrons.

Explanation:

Atoms are composed of a nucleus of protons and neutrons which are orbited by electrons. Diagrams show neat orbits, but they are actually fuzzy. Here is a simplified model of an atom - Carbon.

The identity of an atom depends only on the number of protons, not on the number of neutrons. Many elements have atoms with the same number of protons but different numbers of neutrons. Atoms of an element that have different masses are isotopes (EYE-suh-TOHPS).
