Which prediction regarding the formation of a monatomic ion most likely is not correct?
A)Rubidium (Rb) forms a  1 cation by losing an s electron.
B)Strontium (Sr) forms a  2 cation by losing two s electrons.
C)Scandium (Sc) forms a  3 cation by losing two s electrons and a p electron.
D)Bromine (Br) forms a  1 anion by adding an electron to a p orbital.
E)Sulfur (S) forms a  2 anion by adding one electron to each of two p orbitals.

Question

Quizplus · Accepted Answer

Scandium (Sc) has only one valence electron in the 3d orbital and does not have any p orbitals to lose electrons from. Therefore, it cannot form a F1F1F1S1F1F1F103 cation by losing two s electrons and a p electron.
