The proton is the particle with a positive charge of +1 discovered by Sir Ernest Rutherford. The neutron has a zero charge discovered by Charles Chadwick while the electron has a negative charge of -1 which was a particle discovered by Sir JJ Thomson.

Answer: Proton carries a charge of +1 and has a symbol of 'p'. Electron carries a charge of -1 and has a symbol of 'e'. Neutron does not carry any charge and has a symbol of 'n'.

Explanation:

There are 3 subatomic particles present in an atom: Electron, proton and neutron.

  1. Electrons carries a charge of -1 unit and is represented as 'e'. This particle is located around the nucleus in the orbits.
  2. Protons carries a charge of +1 unit and is represented as 'p'. This particle is present in the nucleus of an atom.
  3. Neutrons does not carry any charge and is represented as 'n'. This particle is present in the nucleus of an atom.

Hence, proton carries a charge of +1 and has a symbol of 'p'. Electron carries a charge of -1 and has a symbol of 'e'. Neutron does not carry any charge and has a symbol of 'n'.
