Helium follows the octet rule

The octet rule is a chemical rule of thumb that reflects the theory that main-group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas. The rule is especially applicable to carbon, nitrogen, oxygen, and the halogens; … Meer weergeven Ionic bonding is common between pairs of atoms, where one of the pair is a metal of low electronegativity (such as sodium) and the second a nonmetal of high electronegativity (such as chlorine). A chlorine … Meer weergeven Many reactive intermediates are unstable and do not obey the octet rule. This includes species such as carbenes, as well as free radicals and the methyl radical (CH3) which has … Meer weergeven Main-group elements in the third and later rows of the periodic table can form hypercoordinate or hypervalent molecules in which the central main-group atom is bonded to more than four other atoms, such as phosphorus pentafluoride, PF5, and Meer weergeven In 1864, the English chemist John Newlands classified the sixty-two known elements into eight groups, based on their physical … Meer weergeven The quantum theory of the atom explains the eight electrons as a closed shell with an s p electron configuration.
