Helium Atom - an overview | ScienceDirect Topics There are four possible states for the helium atom: where the S and P refer, respectively, to the total orbital angular momentum of the two electrons and the leading superscript 1 or 3 uses the multiplicity 2 S + 1 to designate the total spin. The states are referred to, respectively, as singlet and triplet states. Helium Element | History, Uses, Facts, Physical & Chemical Characteristics Occurrence. Helium is present rarely on the Earth. However, it is the 2 nd most abundant element in the universe [2]. The atmospheric content of helium on the Earth is only 5.2 ppm [3]. There is a continuous production of helium on the Earth (via radioactive decay), but it readily escapes the Earth's atmosphere and enter the space. 1.8: Helium Atom - Chemistry LibreTexts Excited States of Helium The lowest excitated state of helium is represented by the electron configuration 1 s 2 s. The 1 s 2 p configuration has higher energy, even though the 2 s and 2 p orbitals in hydrogen are degenerate, because the 2 s penetrates closer to the nucleus, where the potential energy is more negative. Helium - Atomic Number - He - Periodic Table Atomic Number of Helium. Helium is a chemical element with atomic number 2 which means there are 2 protons and 2 electrons in the atomic structure. The chemical symbol for Helium is He. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. The nucleus is composed of protons and neutrons.
