Question

What are the "relative mass" and "actual mass" of the electron, proton, and neutron?​

Answer 1

Explanation:

Protons are the positively charged particles in an atom

Neutrons do not carry any charges

Electrons carry negative charges

 Particles     Charge         Actual Mass       Relative mass compared to proton

 Electrons        -ve             9.11 x 10⁻³¹kg                        $\frac{1}{1840}$

 Protons           +ve             1.67 x 10⁻²⁷kg                        1

 Neutrons            0              1.68 x 10⁻²⁷kg                       1
