Webhelium (He), chemical element, inert gas of Group 18 (noble gases) of the periodic table. The second lightest element (only hydrogen is lighter), helium is a colourless, odourless, and tasteless gas that becomes liquid … WebClick here👆to get an answer to your question ️ A muon of charge - e and mass m = 207me (where me is the mass of an electron) orbits the nucleus of a singly ionized heliumatom (He^ + ). Assuming that the Bohr model of the hydrogen atomcan be applied to this muon - helium system, verify that the energylevels of the system are given by E = - 11.3 KeVn^2
How to Write the Orbital Diagram for Helium (He)?
WebJan 27, 2024 · Helium is the second most abundant element in the Universe, after hydrogen. The nucleus of its most common isotope, helium-4, consists of two protons and two neutrons and is called the α-particle. WebGroup 1 elements have just one valence electron and group 18 elements have eight, except for helium, which has only two electrons total. Thus, group number is a good predictor of how reactive each element will be: Helium (He), neon (Ne), and argon (Ar), as group 18 elements, have outer electron shells that are full or satisfy the octet rule. stray acheter

WebExplanation: Helium only has 2 electrons and therefore it has a configuration of 1s2. Because the 1s orbital is full with 2 electrons and any additional electrons would go in a new energy level. The electron configuration for Helium shows a full outer shell and is Helium is therefore called a Nobel Gas.
