Question

Out of the three subatomic particles Known, which is called universal particle ?

Answer 1

• The three subatomic particles are - Electron (e^- Negative charge)

Proton (P)-positive charge

Neutron (n)- (neutral)

• The mass (9.1 x10^-31 kg) and charge of electron(-1.6 x10^-19 C) is constant .

Therefore Mass and charge of the electron remains constant irrespective of source. Therefore electron is called universal particle.
