The outer octet rule
WebbI dag · Octet Rule As per the octet rule, the maximum number of electrons that can be filled within a valence shell is eight. When they’re less than eight electrons, only then an atom undergo a bond formation either by accepting or donating valence electrons to achieve a stable condition like noble gases.

Webb16 apr. 2024 · The octet rule states that atoms tend to form compounds in ways that give them eight valence electrons and thus the electron configuration of a noble gas. An … Webb10 okt. 2024 · The octet rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell (outer orbital). When atoms have fewer than eight electrons, they tend to react and form more stable compounds. When discussing the octet rule, we do not consider d or f electrons.
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.
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.
