WebSep 2, 2024 · This rule is also called the duet rule. The only elements known to follow the this rule are Hydrogen, Helium and Lithium. ... Following the octet rule results in completely filled s- and p- orbitals in an atom’s outermost energy level. Low atomic weight elements (the first 20 elements) are most likely to adhere to the octet rule. ... WebMar 28, 2024 · Hydrogen and helium have only one electron shell. The first shell has only one s orbital and no p orbital, so it holds only two electrons. Therefore, these elements are most stable when they have two electrons. ...

Can an atom have more than 8 valence electrons? If not, why is 8 …

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; … See more 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 … See more 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 unpaired electron in a non-bonding orbital on the carbon atom and no electron of opposite … See more 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 See more 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 … See more 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 and higher energy levels are empty. For example, the neon atom ground state … See more Some stable molecular radicals (e.g. nitric oxide, NO) obtain octet configurations by means of a three-electron bond which contributes one … See more 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 … See more WebFor hydrogen and helium, unlike most other elements, a full valence shell consists of two electrons rather than eight.
