What is the structural organization of an atom?

Answer 1

A stabe atom has a certain amount of protons (equal to its atomic number), and the same number of neutrons which make up the nucleus. Electrons revolve around the nucleus within their specific domains.

Answer 2

An atom consists of a nucleus at its center, made of protons and neutrons. Electrons orbit the nucleus in specific energy levels called electron shells. The number of protons in the nucleus determines the atomic number of the atom, while the number of neutrons and electrons can vary.

Answer 3

An atom has a positively charged nucleus with negatively charged electrons traveling in orbitals around it.
