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:

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
