What is the charge on Ar ion?
Cl & K ions are isoelectronic with Ar.
What is noble gas notation for carbon?
[He] 2s2 2p2 (the 2's to the right of each letter mean squared)
What ions does not have a noble gas electron configuration S 2 Sr 2 you Cs or Be 3?
Be3+ has only 2 valence electron and not 8.
What is the noble gas figure for S?
[Ne] 3s2 3p4
What outer sublevels are completely filled in a noble gas?
s orbital for helium and p orbitals for other noble gases.
Is S a noble gas?
no S is not a noble gas inorder to become a noble gas u need to have a completely filled outermost shell
What elements is a noble gas H He S or O?
He Helium is a noble gas
What is the charge on Ar ion?
Cl & K ions are isoelectronic with Ar.
What is noble gas notation for carbon?

What ions does not have a noble gas electron configuration S 2 Sr 2 you Cs or Be 3?
Be3+ has only 2 valence electron and not 8.
What is helium 's gas family memeber 's name?
Noble gases
What is the formula of the ion formed when phosphrous achieves s noble gas electrons configuation?
P 3- is the ion with the noble gas configuration.
What is the noble gas figure for S?
[Ne] 3s2 3p4
What is the formula of the ions formed when sulphur gain or lose valence electrons and attain a noble gas configuration?
This is S(2-).
Why helium gas is chemically inactive?
Helium has 2 electrons in its S shell. The most electrons that an S shell can hold is 2 so helium has a full shell, this is why it is sometimes grouped with the noble gas' as they all display full outer shells. The so called noble gas' can also be forced to react under conditions of high temperature and pressure.
What 2 ways of representing an atom's electron configuration?
In full starting with 1s and through each level. The noble gas form, where only the electrons above the highest noble gas configuration are shown, the noble gas is in square brackets. Example chlorine 1s2, 2s2, 2p6, 3s2, 3p5 [Ne]) 3s2 3p5
What ions does not have a noble gas electron configuration S-2 Sr 2 I- Cs or Be 3?
Cs does not have a nobel gas electron configuration, as it contains one valence electron in its outermost s orbital. Be3+ also does have a nobel gas electron configuration, as this occurs when Be has a 2+ charge (the typical Be ion is Be2+).
