It is an isotope of Hydrogen.
helium
The average number of neutrons that a specific element has is equivilent to the element's atomic mass minus the that elements atomic number. For example Helium has 2 neutrons because its atomic mass (4) minus the atomic number (2) is 2.
Helium (He).

There are particular isotopes that have similar number of electrons and neutrons. Some of these isotopes include hydrogen-2, helium-4, carbon-12 and nitrogen-14.
It is normal for the isotope of the element helium. 2He4 isotope has 2 protons, 2 neutrons and 2 electrons.
Helium has 2 protons, 2 neutrons, and 2 electrons.
There are 118 neutrons in the element gold.
If you remove 2 protons and 2 neutrons from gold (Au), the resulting element would be platinum (Pt). Gold has 79 protons and 118 neutrons, while platinum has 77 protons and 116 neutrons.
there are 61 neutrons in a the element silver
An alpha particle has 2 protons and 2 neutrons. That is the same as a helium nucleus.
