Question

Which of the following set of quantum numbers represent maximum number of
electrons in Ni (Nickel)
(1) n = 2, l = 1, m = +1
(2) n = 3, l = 2, m = 0
(3) n= 3, m = 0, S = +1/2
(4) n = 4, m = 0, S = -1/2​

Answer 1

Answer:

Explanation:

The quantum numbers for the last valence electron in nickel are (3, 2, 0, -½). The last electron added is a 3d electron,

so n = 3 and l = 2

Answer 2

IN MY OPINION 'C'  . Should be the right answer

because in 'Ni' last electon come in 3d so it should  option 3 which cover all aspects
