An alpha particle has approximately 4 times the mass of a proton.
A positively charged subatomic particle is called a proton. It is found in the nucleus of an atom and contributes to the overall positive charge of the nucleus.
An alpha particle is a helium nucleus, which consists of 2 protons and 2 neutrons. When an unstable nucleus emits an alpha particle, it loses 2 protons, which means its atomic number will be reduced by 2.
The alpha particle does not have any electrons. This particle is ejected from the nucleus of an atom in what is called alpha decay, and it appears as a pair of protons and a pair of neutrons fused together. The alpha particle is a helium-4 nucleus, and soon after it appears, it will collect a pair of electrons from its environment. But as it appears in the radioactive decay process, it doesn't have any electrons.
Naturally occuring Radon gas decays by alpha particle emission. However, many of the decay chain products have very short half lives, of which some decay by alpha particle emission and others by beta particle emission.
It depends on whether the beta decay sequence is beta- or beta+. In beta-, the atom will gain a proton, changing into neptunium. In beta+, the atom will lose a proton, changing into protactinium.
You will have to tell us what the particle is, but if it is an alpha particle, there are two neutrons in it.

An ALPHA particle may be thought of a a helium nucleus. It contains two protons and two neutrons. An alpha particle is a high speed helium nucleus (He^(2+)).
+2 unit charges - the alpha particle is a helium nucleus.
There are many, but the most commonly known one is the proton.

An alpha particle is composed of two protons and two neutrons.

A proton and neutron are both composed of three quarks. An electron is a fundamental particle and is not composed of smaller particles.
