Octet Rule

[Adilene Gonzalez 1J]

Just to confirm: compounds containing carbon, nitrogen, oxygen, and fluorine are more stable if these atoms have eight valence electrons?

Does someone know what the lewis structure for CSF2 should look like? It is Question 1 from Test 3.

[Chem_Mod]

C is central atom. double bond to S with single bonds to F.

[Megan Phan 1K]

The Lewis structure should have C as the central atom. C should have a double bond with S and single bonds to the 2 Fs.

[Sollie1G]

Yes!! All atoms want eight valence electrons. I think the only exceptions are period 3 and below because they can have expanded octets.

[Courtney McHargue 1I]

Most elements need to have a complete octet of valence electrons in order to survive and be stable. Only certain elements such as sulfur, phosphorus, chlorine and silicon can hold more than 8 valence electrons and form a stable expanded octet and elements such as hydrogen can only handle 2 valence electrons.
