Question

Give at least eight properties of alpha particles.

Answer 1

Alpha particles are helium nuclei, they have two positively charged protons and two neutrally or in some cases zero charged neutrons, and  have an overall charge of 2+. Protons and neutrons each have a mass of 1 atomic mass unit, and so an alpha particle has a total mass of 4.

This aren't 8 properties, but they are all I know. Hope it helped.
