Solution

Atom:

  • An atom is composed of three subatomic particles that are electrons, protons, and neutrons.
  • Protons and neutrons are present inside the nucleus of an atom while electrons revolve around in the circular orbits

Importance of subatomic particles:

Protons:

  • Protons are particles that are positively charged and are also located in the nucleus.
  • The proton accounts for the atom's atomic number and determines the identity of the atom.

Electrons:

  • Electrons are particles that are negatively charged.
  • An atom has no charge as it has an equal number of electrons and protons.
  • Electrons are responsible for the bond formation between atoms.

Neutrons:

  • Neutrons are neutral (no charge) particles contained in the core (the nucleus) of the atom.
  • Protons, including neutrons, give the atom mass but are not involved in chemical reactions.
