A helium nucleus - more precisely, a helium-4 nucleus - is called an alpha particle. The corresponding decay would be called alpha decay.
This is the alpha radioactive decay.
An alpha particle is identical to the nucleus of Helium atom
The two types of radioactive decay are alpha and beta. Generally, in alpha decay the nucleus will lose 2 protons and 2 neutrons (it's a helium nucleus). Beta decay involves a neutron losing an electron and becoming a proton, so the atomic mass remains the same, but the atomic number increases by one since there is another proton.
Yes. Alpha particles can be a product of radioactive decay, and alpha particles are simply Helium nuclei. Unless they interact with other atoms, they will tend to pick up stray electrons (they need two) and become stable 4He atoms.

The radioactive alpha particle has the same structure as the atomic nucleus of helium. They are usually formed and emitted during alpha decay.
An alpha particle, one of the possible emissions in radioactive decay.
No, beta particles consist of high-energy electrons or positrons that are emitted in certain types of radioactive decay. Helium nuclei have two protons and two neutrons and are called alpha particles.
Another name for a beta particle is an electron. It is a high-energy, high-speed particle that is emitted during the radioactive decay of certain elements.
Helium is extremely stable and non radioactive
No, alpha decay does not directly produce helium atoms. Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle, which consists of two protons and two neutrons. This alpha particle is the same as a helium-4 nucleus, but it is not considered a helium atom until it captures electrons and becomes electrically neutral.
When a hydrogen-3 nucleus undergoes radioactive decay, it emits a beta particle (specifically an electron) and an anti-neutrino to transform into helium-3.
The nuclear reaction that results in a single nucleus undergoing a decrease in atomic number and the release of a helium nucleus is called alpha decay. In this process, an unstable nucleus emits an alpha particle (helium nucleus) which consists of two protons and two neutrons, causing the original nucleus to decrease in atomic number by 2.

When a radioactive nucleus emits an alpha particle, it decreases by two protons and two neutrons. This results in a new nucleus with a lower atomic number by 2 and lower mass number by 4. The emitted alpha particle is a helium nucleus (2 protons and 2 neutrons) and carries a positive charge.
The alpha particle has a composition identical to a helium nucleus, specifically, the nucleus of helium-4. The alpha particle, however, is a product of radioactive decay, and is usually moving pretty fast. When we speak of helium nuclei, we are usually speaking of things that are much less energetic.
