Question

What is the Noble gas notation of sulfur (S)?
I know it is one of the first 2 but I'm not sure which one.
\([Ne]~2s^22p^4\)
\([Ne]~3s^23p^4\)
\([Ar]~3s^23p^4\)
\([Mg]~3p^4\)

Answer 1

Answer 2

@Preetha

Answer 3

3s2, 3p4

Answer 4

can you explain why?

Answer 5

1s2,2s2,2p6, 3s2,3p4 = 16 electrons

[Ne] = 1s2,2s2,2p6 =10 electrons
what is the part that you dont understand

Answer 6

so is it just what is on sulfur that isnt on neon?

Answer 7

Yes, in place to write all the sequence of levels and orbitals with all the electrons you replace until the previous noble gas configuration and write the noble gas symbol between brackets.

Answer 8

ok thank you
none of my courses really explain anything so i am really having to figure out most things on my own

Answer 9

To understand this concept, it's useful to write an example configuration. Let's write a configuration for Zinc (atomic number 30) using noble gas shorthand. Zinc's full electron configuration is: 1s2 2s2 2p6 3s2 3p6 4s2 3d10. However, notice that 1s2 2s2 2p6 3s2 3p6 is the configuration for Argon, a noble gas. Just replace this portion of Zinc's electron notation with Argon's chemical symbol in brackets ([Ar].)
So, Zinc's electron configuration written in shorthand is [Ar]4s2 3d10.

Answer 10

okay, i have no clue how to do this...sooo i think @Cuanchi has this under control lol

and @sleepyjess in the online school im in, they provide us with barily any resources so we have to find everything on our own (very stressful lol)

Answer 11

here is a link to some flashcards if you want it (not very explanitory but every lil bit counts)
