Question

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

Answer 1

The answer to your question is the first choice

Step-by-step explanation:

Data

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
