An atom is the smallest particle of any substance that can take part in chemical reactions.
Atoms are made up of three small particles which are protons, neutrons and electrons.
Protons are the positively charged particles in an atom.
Electrons are the negatively charged particles in an atom.
Neutrons do not carry any charges.
The atomic space is made up of a tiny nucleus and a large space filled with orbital electrons.
The nucleus is made up of both protons and neutrons together.
