Question

. Alpha Particles a. What is the mass number of an alpha particle? b. What is the identity of an alpha particle? c. What kind of charge does an alpha particle have?

Answer 1

hope it helps you
an alpha particle is basically a helium nucleus...so it contains 2 protons and 2 neutrons. So atomic mass number is 4..I.e. 2 protons + 2 neutrons

Answer 2

Alpha particles are usually produced by alpha decay which consisted of two protons and two neutrons.

They are identical to the nucleus of helium-4.

The alpha particle is represented as α or α²⁺. In addition, as it is identical to nucleus of helium, it is also represented as He²⁺.

As it only posses two protons and two neutrons but no electrons, the overall charge of alpha particle is +2.

The mass number of an element refers to the total number of neutrons and protons in the nucleus. Hence, the mass number of alpha particle would be 4
