The outer octet rule
Webb23 feb. 2024 · The Octet Rule. For an atom to be neutral, it must contain the same number of electrons and protons. So, in a neutral atom, the number of protons in the nucleus is equal to the number of electrons surrounding it. This was the starting-point for the work of Gilbert Lewis, an American chemist at the University of California, Berkeley. WebbOther articles where octet rule is discussed: chemical bonding: Contributions of Lewis: …are expressed by his celebrated octet rule, which states that electron transfer or …

Webb2 nov. 2016 · The octet rule states that atoms tend to gain or lose electrons in their outer levels until they acquire eight electrons and are then unreactive. Ultimately, the atoms become more stable if they can get a full energy level. Helium has a full energy level with 2 electrons so it doesn't follow the octet rule. WebbThe octet rule is only applicable to the main group elements. The molecules of the halogens, oxygen, nitrogen, and carbon are known to obey the octet rule. In general, the …
Webb13 nov. 2012 · The octet rule states that elements gain or lose electrons to attain an electron configuration of the nearest noble gas. Here is an explanation of how this works … 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 … Visa mer 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 atom has … Visa mer The quantum theory of the atom explains the eight electrons as a closed shell with an s p electron configuration. A closed-shell configuration is one in which low-lying energy levels are full … Visa mer Some stable molecular radicals (e.g. nitric oxide, NO) obtain octet configurations by means of a three-electron bond which contributes one … Visa mer The octet rule is only applicable to main-group elements. Other elements follow other electron counting rules as their valence electron configurations are different from main-group elements. These other rules are shown below: • The … Visa mer In 1864, the English chemist John Newlands classified the sixty-two known elements into eight groups, based on their physical properties. In the late 19th century, it was known that coordination compounds (formerly called "molecular … Visa mer 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 an … Visa mer 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 Visa mer
