WebMar 20, 2024 · Now a new team of researchers has offered an explanation: Helium manages to combine with other atoms without making any chemical bonds—that is, without sharing or exchanging any electrons. WebThe hydrogen valence electrons act like helium, element number 2. There is 1 hydrogen valence electron and H forms 1 bond. The simple logic is that 1 + 1 = 2 for hydrogen. Helium and hydrogen are exceptions to the octet rule, and some say the “duet rule” applies. H and He are stabilized with 2 electrons, not an octet. (Duet means 2). green and brown house colors

WebThese four electrons can be gained by forming four covalent bonds, as illustrated here for carbon in CCl 4 (carbon tetrachloride) and silicon in SiH 4 (silane). Because hydrogen only needs two electrons to fill its valence shell, it is an exception to the octet rule. WebHelium and neon never form molecules. They have completely filled electron shells with no have-filled orbitals available for making covalent bonds and they have very high ionization energies so they don't form ions. Argon Chemistry Atomic argon has a filled shell configuration with filled 3s and 3p orbitals.
