Octet Rules

[NicoJones_1B]

What are the guidelines for the octet rule? Is it referring to the rule all atoms are only capable of having 8 valence electrons?

[jeffreygong1I]

It just means that most atoms prefer to have(are most stable with) eight valence electrons, although there are exceptions...

[Brianna Becerra 1B]

The guideline for the octet rule is that atoms share valence electrons until a noble-gas configuration is reached. The exceptions mentioned in lecture to the octet rule are H, He, Li and Be.

[Tanmay Singhal 1H]

there are also some atoms that can have more than 8 valence electrons. I believe phosphorous is one of these.

[CalvinTNguyen2D]

Just to add on, other elements like sulfur, silicon, and chlorine can have expanded octets!

Yup, I agree.

[Yiyang Jen Wang 4G]

It just means that most elements prefer to have 8 valence electrons in order to stay stable. But many can have more or less than 8 especially when they bond to other elements.

[Nyari Muchaka_Discussion 4A]

Octet rule basically means that atoms are more stable when they have a full valence electron. In the s orbital, electrons can fit two electrons, in the p orbitals, the atom can fit six electrons, in the d orbital ten electrons, and in the f orbital 14 electrons. All atoms after beryllium have both an s and p orbital, and thus want a full valence shell of eight electrons(2+6=8), so they will either try to take electrons or lose electrons to empty the shell entirely depending on their electron affinity.

I believe that it must have 8 valence electrons to be stable!
