Question

what is an alpha particle? why are there no electrons around it?

Answer 1

In fact, an alpha particle really is a nucleus - it's the same as the nucleus of a common atom of helium - but it doesn't have any electrons around it, and it's traveling very fast. Alpha particles are a type of ionizing radiation. To describe the production of alpha particles, we have to define radioactive decay.

Answer 2

Alpha particles are nothing but He+2 ions

Alpha particles were used for the discovery of the nucleus of an atom by Rutherford .
