Explanation:

The smallest part of a substance that cannot be chemically decomposed. In other words, an atom is the smallest and most indivisible unit that makes up matter.

Each atom has a nucleus, which is the center, made up of protons (which are positive particles) and neutrons (which are uncharged particles). The electrons (negative particles) move around the nucleus through the orbitals. The differences between the amounts of protons, neutrons and electrons is what characterizes each element.
