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.
There're two particles in the atom nucleus (protons and neutrons)
Protons and electrons.
protons and electrons.
Electrons and protons.
Protons and electrons in an atom always have the same number, which determines the atom's overall charge. The number of protons is equal to the atomic number of the element, while the number of electrons is equal to the number of protons in a neutral atom.
An atom with 35 protons is iodine, which is a neutral atom. In a neutral atom, the number of electrons equals the number of protons, so it also has 35 electrons. Therefore, an atom with 35 protons has 35 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.
