How many bonds can helium form? - Answers

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).

WebApr 2, 2024 · Each H can form only a single covalent bond, leading to the formation of H − H molecules, which are often also written as H 2 molecules. These H − H molecules are themselves attracted to one another through LDFs. We can compare energy associated with the H − H covalent bond and the H 2 − H 2 IMF. WebAug 19, 2024 · These 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 and only needs to form one bond.
