It is helium, specifically the helium-4 isotope, that is composed of two protons and two neutrons.
In a He-4 atom, the nucleus contains two protons and two neutrons. The protons have a positive charge, while neutrons are neutral.
the you and the stupid! oh wait that is the same thing!
If you build an atom using two protons, two neutrons and two electrons you would build an atom of Helium. To be more-precise, this would create Helium-4 the common isotope of Helium.
neutrons and protons electrons are on the outer shell
The two parts found in the nucleus of an atom are protons and neutrons. Protons have a positive charge, while neutrons have no charge.
Protons and neutrons are the two particles that are in the nucleus of an atom. Electrons orbit around the atom
Proton and neutron.
The two principal components of an atom at a subatomic level are Protons and Neutrons. Protons are subatomic particles with a mass of 1 and a charge of 1+ Neutrons are subatomic particles with a mass of 1 and a charge of 0 or neutral
Protons and neutrons are the two atomic particles found in the nucleus of an atom. Protons have a positive charge, while neutrons have no charge and contribute to the mass of the nucleus.
protons and neutrons are located in the atom's nucleus.
The two subatomic particles you add together to get the mass number of an atom are protons and neutrons. Protons have a positive charge, while neutrons have no charge, but together they contribute to the mass of an atom.
Nucleus (and it consists of protons and neutrons).
