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

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

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.

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

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

Yup, I agree.

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.

Re: Octet Rules
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.
