A.5, 0, 0, +
B.5, 1, 0, +
C.5, 1, 1, +
D.6, 0, 0, +

Answer 1

have you written an electronic configuration?

Answer 2

Nandan, which group is Rubidiium in? And as Aaron says, do you have any idea what the electronic config is? Is it 5s1 or 6s1? Then you have to know what the four numbers stand for. Find a periodic table and locate Rb.

Answer 3

5s1

Answer 4

The correct set of quantum numbers will be: 5, 0, 0, +½ or -½
