Respuesta :
[Ar] 3s^23p^6 since Ar is in period 3 and have all the orbitals filled with electrons
Answer;
-[Ar] 3s^23p^6
Explanation;
-Noble gases are elements in group 8 of the periodic table, they contain an octet configuration.
-Argon (Ar) is an example of noble gases that belongs in period 3 of the periodic table and in group 8. Its configuration is 1s^2 2s^2 2p^6 3s^2 3p^6. The p orbital can hold up to six electrons. We'll put six in the 2p orbital and then put the next two electrons in the 3s. Since the 3s if now full we'll move to the 3p where we'll place the remaining six electrons.
