What are atoms?

Answer 1

n chemistry and physics, an atom (Greek ἄτομος or átomos meaning "indivisible") is the smallest particle of a chemical element that retains its chemical properties. (Since until the advent of quantum mechanics dividing a material object was invariably equated with cutting it, átomos is usually translated as "indivisible".) Whereas the word atom originally denoted a particle that cannot be cut into smaller particles, the atoms of modern parlance are composed of subatomic particles:

* electrons, which have a negative charge, a size which is so small# as to be currently unmeasurable, and which are the least heavy (i.e., massive) of the three;
# protons, which have a positive charge, and are about 1836 times more massive than electrons; and
# neutrons, which have no charge, and are about 1839 times more massive than electrons.

Answer 2

Atoms are particles that make up molecules. They can be a nuetron, proton, or electron. The different combinations choose whether it is, say, hydrogen, or helium. They are made up of even smaller particles called quarks and gluons.
