It would by definition be Helium (atom number = number of protons = 2) but the nucleus of the stable isotope 4He also contains 2 neutrons (the mass number = total number of p's and n's = 4)
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.
No, an atom cannot gain or lose protons. Protons are the positively charged particles within the nucleus of an atom, and changing the number of protons would change the atom's identity. However, atoms can gain or lose electrons, which affects their charge but not their identity.
Adding protons would make it a different element. If Electrons were added to an atom, it would start behaving like another element. For example Fluorine would try to be more like Neon. All elements want balance, so they get as close in relation to these noble gases as possible by sharing, stealing, and giving up electrons
The atomic number of carbon is 6. Therefore, carbon has 6 protons. If it gained two more protons, it would have 8 and would become oxygen.
If the atom has more electrons than protons than the atom will be negative.
Germanium has thirty two protons. If two were removed, the atom would have thirty protons, making it Zinc.
If you remove two protons from a germanium atom, it would become a selenium atom. This is because germanium has 32 protons, while selenium has 34 protons.
The atom in a normal state would have two protons to match the two electrons, making the overall charge zero. If the atom is an ion, it would have an mismatched number of protons and electrons, giving it a positive or negative overall charge.
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.
Protons and neutron
If you remove two protons from a germanium atom, it would become a gallium atom. Gallium has atomic number 31, while germanium has atomic number 32. By removing two protons, the atomic number decreases by two, hence the change to gallium.
Neon atoms have 10 protons.
Nucleus (and it consists of protons and neutrons).
Helium
The number of protons varies for different elements. For example, Hydrogen has only one proton in each atom. That's what makes hydrogen hydrogen. If it had two protons, it would be helium. If there were no protons, then it wouldn't be anything.
