There is no such thing as a hydrogen atom with 2 protons in its nucleus; a nucleus with 2 protons would be a helium atom. Deuterium ([math]) is an isotope of hydrogen with one proton and one neutron which due to an even number of neutrons, doesn’t produce a visible signal. In previous years, Rutherford had discovered that the hydrogen nucleus (known to be the lightest nucleus) could be extracted from the nuclei of nitrogen by atomic collisions. Hydrogen can have any number of electrons and still be hydrogen. The proton is not an elementary particle but a compound particle. For example, hydrogen has the atomic number 1; all hydrogen atoms have 1 proton in their nuclei. The number of protons in the atomic nucleus is what determines the atomic number of an element, as indicated in the periodic table of the elements. The chemical symbol for Hydrogen is H. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. The number of protons is equal to the number of electrons, unless there’s an ion superscript listed after the element. , Emily H, No Comment, June 30, 2016 Each mole has a Avogadro's number of atoms or atoms.
