Question

The charge on an alpha particle is a
doubly charged​

Answer 1

α-particles are doubly-charged helium ions. Since they have a mass of 4µ, the fast-moving α-particles have a considerable amount of energy.

Answer 2

Explanation:

Alpha particles are composite particles consisting of two protons and two neutrons tightly bonded together. An alpha particle is identical to the nucleus of a doubly ionised helium atom. Alpha particles have high ionizing capacity
