Question

Comparison of mass of proton alpha particle electron

Answer 1

Since the alpha particle is nothing but positively charged helium nuclei, it has charge of two time of that of the proton, as it is constituted of 2 protons.The rest mass of the alpha particle amounts to 6.64424. ... Now it is known that the mass of proton is e(approx. 1.67×10^-27 kg).
