WebOne of the most important reactions that occur in the star's core is the proton-proton chain reaction. This reaction is responsible for converting hydrogen into helium and releasing energy in the form of gamma rays, neutrinos, and positrons. The proton-proton chain reaction can be represented by the following equation: 4p → 4He + 2e+ + 2νe + γ WebJan 30, 2024 · Excited States of Helium. The lowest excitated state of helium is represented by the electron configuration 1s 2s.The 1s 2p configuration has higher energy, even though the 2s and 2p orbitals in hydrogen are degenerate, because the 2s penetrates closer to the nucleus, where the potential energy is more negative. When electrons are in …
WebApr 2, 2024 · The weakness of these interactions means that at higher temperatures, above 4 K, helium atoms do not “stick together”. Helium is a gas at temperatures above 4 K.
