WebA hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the baryonic mass of the universe. [1] WebWe start with a single hydrogen atom (atomic number 1), which consists of one proton and one electron. Referring to [link] or [link], we would expect to find the electron in the 1 s orbital. By convention, the \ ( {m}_ {s}=+\frac {1} {2}\) value is usually filled first. The electron configuration and the orbital diagram are:
