Q1: What are Atoms?
The proton, neutron, and electron make up an atom, which is the smallest recognised division of a chemical element. The central nucleus, which consists of protons and neutrons, holds 99% of the atom’s mass. Negatively charged electrons whirl about the nucleus in a variety of orbital shells. The atomic number refers to the number of protons in a nucleus. Because the number of protons in an atom equals the number of electrons, atoms have no overall charge. An ion is created whenever an atom gains or loses electrons.
