OCTET RULE
What exactly does the octet rule mean? When forming ions does there have to be 8 electrons available after removing/adding an electron?

Re: OCTET RULE
Octet rule arises from the fact that stability is reached when you have a fully occupied valence electron shell. For most atoms, the valence shells involve s and p orbitals, thus you need 8.

Re: OCTET RULE
Octet rule means that when atoms combine to form molecules, they each lose, gain, or share valence electrons until they attain/share eight electrons.
Re: OCTET RULE
it should be noted that there are exceptions to the octet rule. For example, Hydrogen is most stable when it has 2 electrons in its valence shell.

Re: OCTET RULE
When atoms are combining covalently, meaning that they are sharing electrons, they want to get a full outer orbital of 8 electrons and become stable.

Re: OCTET RULE
The octet rule just refers to the atoms wanting 8 electrons in order to become stable, but there are many exceptions to this rule when you reach the d orbital, or the 3rd row.

Re: OCTET RULE [ENDORSED]
Octet rule is due to the atoms wanting to be stable. With 8 electrons, its shell will be full and that stabilizes the electrons. This is similar to how when we did orbitals, 3d^9 would take an electron from 4s^2, because it wants to fill up it's orbital to be full (3d^10). So in the case of electrons, most of them need 8 electrons to fill up.

Re: OCTET RULE
I always think of the octet rule as, most, elements always wanting a full 8 electrons to be as stable as possible. They all want to be full like the noble gases.
