More than 8 valence e-

Postby Nick Lewis 4F » Sun Oct 27, 2019 11:51 pm

Can someone explain why sulfur and those other atoms can take more than 8 electrons? I remember Dr. Lavelle had a good explanation in class but I am having trouble coming up with his explanation while trying to study.

Sulfur, phosphorous, and chlorine are examples of an expanded octet because starting in this row, these atoms have a d orbital which can hold extra electrons. In the normal state, they are not usually all filled so when it comes time to share electrons they are able to store more in the d orbital. Hope this helps!

everything in the 3rd period and above can have more than 8 valence electrons because of the extra sub shells

They are examples of expanded octets (expanded its valence shell). For phosphorus, there is the 3d subshell available and the d-orbitals that can accommodate for more valence electrons. This allows for extra pair of electrons to occupy the valence shell which means there are more than 8 valence electrons.

This is a question: so in high school I thought all atoms had 2 electrons in the first sub shell, and in all of the next sub shells the valence electrons were 8. So do all atoms that have a d orbital are able to have more than 8 electrons in a Sub shell?

Only the 2nd row in the periodic table can have a maximum of 8 valence electrons because it has the 2s and 2p orbitals

the d orbital allows these atoms to hold extra electrons

Why can d orbitals carry extra electrons?

Once you get past phosphorus, those elements have the d orbitдal in addition to the s and p orbitals, allowing the elements to old additional electrons in their shell
