Helium.
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.
When two protons and two electrons are removed from a sulfur atom, it forms a helium ion (He2+).
The number of protons in the atom's nucleus and the total number of electrons in the electron shells of that atom.
If an atom has 23 protons, then it will also have 23 electrons, assuming the atom is neutral. Electrons and protons have equal and opposite charges, so in a neutral atom, the number of protons equals the number of electrons.

protons and electrons.
An atom of ruthenium contains 44 protons and 44 electrons. This is because the number of protons in an atom determines its identity, and for a neutral atom, the number of protons equals the number of electrons.
Protons and Electrons. Protons are positively)+) charged and electrons (-) are negatively charged. For an atom to be neutrally charged the number of protons MUST equal the number of electrons. The number of positives must equal the number of negatives. When these number are NOT equal ; loss/gain of electrons, then the atom is named an ION.
The number of protons per atom, and the number of electrons per atom.
An atom has the same number of electrons and protons. Protons are positively charged particles found in the nucleus of an atom, while electrons are negatively charged particles that orbit the nucleus.
