question 8 of 33 which sublevels contain valence electrons in an atom of argon (ar)? the periodic table a. 3s and 2p b. 3s and 3p c. 2s and 3d d. 4s and 3p

Answer

Brief Explanations:

Argon has an atomic number of 18. Its electron - configuration is 1s²2s²2p⁶3s²3p⁶. The outermost shell (valence shell) is the third shell (n = 3), and the sub - levels in this shell are 3s and 3p which contain the valence electrons.

Answer:

B. 3s and 3p
