The electron configuration of atoms of a noble gas could be: 1s 22s 22p 6
1s 22s 22p 3
1s 22s 2
1s 22s 22p 4
none of the above

The answer to your question is the first choice

 Noble gas electron configuration

Noble gases are located in group Vlll in the periodic table, this means that they have eight electrons in their outermost shell.

Then, to solve this problem count the number of electrons in this shell.

1s²2s²2p⁶       This configuration has 8 electrons in the outermost shell

                         This is the right answer

1s²2s²2p³         This electron configuration has 5 electrons in their outermost shell    

1s²2s²                This electron configuration has 2 electrons in their outermost shell.  

1s²2s²2p⁴          This electron configuration has 6 electrons in their outermost shell.

none of the above

the increase of protons   hope this

i do not get it   at all
