it is similar to an alpha particle
Yes Helium has two protons and two electrons in its nucleus.
Helium has two neutrons and two protons in its nucleus.
2 protons 3 neutrons
The nucleus of a helium atom contains two protons and two neutrons.
That is alpha decay. The particle is identical to a helium nucleus.
Alpha radiation is made up of alpha particles, which are helium nuclei consisting of two protons and two neutrons. These particles have a positive charge and are relatively large and heavy compared to other types of radiation.
An atom with 2 protons is naturally Helium. Therefore, this isotope would be called helium - 5 because it has 5 particles in its nucleus, 2 protons and 3 neutrons.
When helium capture occurs with a carbon-12 nucleus, the result is oxygen-16. This is because the combination of a helium nucleus (2 protons and 2 neutrons) with a carbon-12 nucleus (6 protons and 6 neutrons) produces an oxygen-16 nucleus (8 protons and 8 neutrons).
Alpha rays are called helium nuclei because they consist of two protons and two neutrons, which is the same composition as a helium nucleus. When an atom undergoes alpha decay, it emits an alpha particle, which is essentially a helium nucleus that is ejected from the atom.
An alpha particle has 2 protons and 2 neutrons. That is the same as a helium nucleus.
The helium nucleus is larger than the proton. The He nucleus consists of two protons, and one (rarely) or two (most commonly) neutrons. (These are He-3 and He-4, respectively.) That would make the helium nucleus a multiple of three or four times the mass of that of a single proton.
There are 2 neutrons in a helium atoms nucleus , along with two protons.
