Do all atoms have protons?

As far as the elements known to us are concerned, all the of the atoms have both protons and neutrons in the nucleus. The quantity of the protons and neutrons varies according to the type of element and its isotopes. read more

Not all atoms necessarily have electrons or neutrons because they can lose them in chemical reactions. (Think of how sodium loses electrons when it reacts with chlorine.) However, singular atoms of any given element (except hydrogen) always have protons, neutrons, and electrons. read more

The quantity of the protons and neutrons varies according to the type of element and its isotopes. It is not possible to have a stable atom without the presence of protons. read more

Protons all have the same mass; each proton's mass is 938.27 megaelectronvolts, or 1.6726231*10-27 kilograms. In fact, all protons are identical, as are all electrons and all neutrons, though each of these three subatomic particles is distinct from the other two kinds. read more
