An atom is the smallest particle of an element, consisting of sub-atomic particles: electrons, protons, and neutrons. Electrons have a negative charge and orbit the nucleus, while protons are positively charged and with neutrons, contribute to the atom's mass. Neutrons are neutral and also located in the nucleus, contributing to the overall mass of the atom.

WHAT IS AN ATOM?
An atom: is the smallest particle of an
element
 It is made up of sub-atomic particles
namely; electrons, protons and neutrons.

3. ELECTRONS
 These are the negatively charged sub-atomic particles.
 They revolve around the nucleus in fixed paths called
orbits/shells.
 The number of electrons equals the number of protons
in a neutral atom.
 They do not contribute to the mass of an atom.

4. PROTONS
 These are positively charged particles of an atom.
 They are found inside the nucleus.
 Together with neutrons, they make the mass of an atom
 They are equal in number with the electrons

5. NEUTRONS
 These are neutral particles of an atom, that is they have no charge.
 They are found inside the nucleus.
 They contribute to the mass of an atom.
