Answer 3

A.
9 electrons, 11 protons, 9 neutrons; 0 electrons are needed to completely fill the outer shell of this atom

B.
9 electrons, 9 protons, 11 neutrons; 1 additional electron is needed to completely fill the outer shell of this atom

C.
9 electrons, 9 protons, 11 neutrons; 0 electrons are needed to completely fill the outer shell of this atom

D.
9 electrons, 11 protons, 9 neutrons; 1 additional electron is needed to completely fill the outer shell of this atom

Answer 4

The outermost shell of an atom has to reach 8 electrons to fully fill it.
The number of protons is equal to number of electrons.

Having this is mind, what do you think the answer is?
