Hey mate...
here is your answer
Alpha particle consist of two protons and two neutrons bound together into a particle identicle to a helium-4 nucleus
Hope it helps you!!!!

hey here is your answer
Alpha particles consist of two protons and two neutrons bound together into a particle identical to a helium nucleus. They are generally produced in the process of alpha decay, but may also be produced in other ways. Alpha particles are named after the first letter in the Greek alphabet, α. The symbol for the alpha particle is α or α2+. Because they are identical to helium nuclei, they are also sometimes written as He2+indicating a helium ion with a +2 charge (missing its two electrons). If the ion gains electrons from its environment, the alpha particle can be written as a normal (electrically neutral) helium
So now what is left is nothing but the Nucleus of the helium atom and there you go my friend an alpha particle.
Thus an alpha partical is a doubly charged helium atom.

Its an helium nuclie with mass 4 times of proton and charge 2 times of proton.
Now an obvious question comes to minds- how does it form? Why is a particle formed by stripping away all electrons from a noble gas configuration so common?
The answer lies in quantum mechanics.
In the realm of the smallest, mechanics of particle are pretty different than our scales. Everything is in a delocalised state, meaning no particle has a definite position of residing instead they have a PROBABILITY of existing anywhere in a specific region. This is called a wavefunction and it collapses into a specific location as we make a measurement.
For heavier elements, i.e, nucleus with higher no of nucleons, we can suppose that there exists an alpha particle independent to the nucleons inside the nucleus. This is held together by the strong nuclear force.
Now due to the probablistic behavior of the alpha particle there is a slightest probablity that it exists outside the nucleus and thus it comes out of the , Professor Emeritus, Dept. of Physics & Astronomy, Univ. of … · Author has 943 answers and 1.4m answer views
Alpha particle is just a helium nucleus.
The usage of this term is historical, as when it was first discovered (by Rutherford and Villard, in 1900), it was not identified as helium nucleus. They discovered that radiation from a radioactive source had three components - one positively charged, negatively charged and neutral. Rutherford named them alpha, beta and gamma, in increasing order of penetration ability.
Rutherford further measured its charge-to-mass ratio, which came out exactly the same as what would be expected of a doubly charged helium ion. The definitive evidence that alpha particles are helium nuclei came only in 1907 when Rutherford and Royds allowed them to combine with electrons and then measured their spectrum. By that time, the term "alpha particle" had stuck.
Nowadays the terms "alpha particle" and "helium nucleus" are used interchangeably. The usage of "alpha particle" is especially popular in nuclear physics.
