helium
Protons, neutrons and electrons
An isotope is a particle that has an unequal number of protons and neutrons. Isotopes of an element have the same number of protons but different numbers of neutrons. These variations in the number of neutrons result in different atomic masses for isotopes of the same element.
Alpha radiation.
No Alpha radiation is essentially a helium nucleus - a couple of protons and neutrons bound together as a particle Beta radiation is an electron or positron - still a particle but not the same kind of particle as alpha.
alpha particle dont ask why cuz i dont know
Alpha decay is a kind of radioactive decay in which an alpha particle is emitted from an atom. An alpha particle consists of two protons and two neutrons. Therefore, when an atom of an element undergoes alpha decay, it loses two protons, which changes the atom from one element to another. This is because each different element is identified by the number of protons in its atomic nuclei.

Zinc has 30 protons since its atomic number is 30. This also means that it has 30 electrons to balance the positive charge from the protons. The number of neutrons in an atom of zinc can vary based on the isotope, but a typical zinc atom has around 35 neutrons.
Neutrons are electrically neutral particles, meaning they carry no charge. They are found in the nucleus of an atom along with positively charged protons. The lack of charge allows neutrons to play a crucial role in stabilizing the nucleus by mitigating the repulsive forces between protons.
Protons are positively charged (+) and neutrons don't hold any charge.
Polonium, which has an atomic number of 84, decays to astatine, which has an atomic number of 85, a negative beta particle is emitted.
It is very unusual for one kind of atom to become another kind atom, however it does happen in radioactive processes. Every element is characterized by a distinct number of protons. For example, all hydrogen atoms have 1 proton, all helium atoms have 2 protons, etc. Atoms also include electrons and neutrons. However, adding or removing electrons or neutrons does not change the kind of atom. For example, a helium atom with 2 electrons or 1 electron is still a helium atom. Alpha decay is an example of a radioactive process in which the number of protons changes (and therefore the kind of atom changes). An alpha particle includes 2 protons and 2 neutrons. When it is expelled from an atom, a new kind atom is formed. This occurs when a uranium atom (92 protons) is changed into a thorium atom (90 protons) + an alpha particle.
