This does not happen in a single decay event. It requires two separate decay events.
alpha particle
An alpha particle is a positively charged nuclear particle consisting of two protons bound to two neutrons. The atomic number of an atom decreases by 2 and the mass number decreases by approximately 4 when an alpha particle is ejected.
Because an alpha particle is bigger than a helium or hydrogen atom.
An alpha particle is the nucleus of a helium-4 atom, that is, it consists of two protons and two neutrons.
2 neutrons and 2 protons (this is what an alpha particle is made up of).
The nucleus of a helium atom is called an alpha particle. The electromagnetic waves emitted by a nucleus are called gamma rays.
An alpha particle is identical to the nucleus of Helium atom
It soon captures electrons, becoming an ordinary helium atom.

Alpha radiation is essentially a Helium nucleus (not the whole atom, apha particles don't have electrons on them). An alpha particle is just two protons and two neutrons and as a result they also have a relative charge of +2.

No, it is identical to that of a helium atom.
A radiation particle consisting of two protons and two neutrons is called an Alpha Particle. Alpha Particles have the same structure as a Helium nucleus. There are three forms of radiation, Alpha (Helium nucleus), Beta (a lone electron) and Gamma (an Electromagnetic wave).
