Step-by-step explanation:
Atoms are generally made up of three fundamental particles which are the protons, neutrons and electrons.
Protons are the positively charged particles within an atom.
Electrons carry negative charges.
Neutrons do not carry any charges.
When an atom is neutral, the number of protons and electrons within the atom is the same.
A charged atom will have a difference in the number of protons and electrons they contain.
