b. an atom's outer energy level doesn't have the maximum
c. an atom's nucleus has the same number of protons as neu
d. an atom's outer energy level is filled.

b.an atom’s outer energy level doesn't have the maximum number of electrons.

Explanation: I hope this helps.

B

Explanation:

Octat rule:It is the ability to have 8 electrons in last shell

An atom is said to be stable ,and on lower energy it must fill the last shell.

To complete last shell an atom tends to shair or transfer electrons.
