OCTET RULE

Postby april_bussey_1C » Sun May 13, 2018 10:27 pm

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

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.

okay so the octet rule fully applies when we are trying to stabalize an atom?

Yes, typically when an atom is not stabilized the octet rule should be applied.

Octet rule means that when atoms combine to form molecules, they each lose, gain, or share valence electrons until they attain/share eight electrons.

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.

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.

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.

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.

in simple terms, the octet rule is having the 8 electrons full to become more stable

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.
