Question
Which of the following subatomic particle is lightest?
✓
Answer
Alpha particle has highest mass of the given option which is he rest mass of the alpha particle amounts to $6.64424 \times 10^{−27}kg.$
Mass of neutron is $1.0086654\ \text{a.m.u.}$
Mass of electrons $= 9.10938291 \times 10^{−31}$ kilograms.
Hence mass of alpha particle is greatest.
