Question
No. of visible lines when an electron returns from 5th orbit to ground state in H spectrum :Which of the following statement(s) is (are) correct?
Options
A.The electronic configuration of Cr is [Ar] (3d)5 (4s)1. (Atomic number of Cr = 24)
B.The magnetic quantum number may have negative values.
C.In silver atom, 23 electrons have a spin of one type and 24 of the opposite type. (Atomic number of Ag = 47)
D.None of these
Solution
(A) 24Cr : [Ar]3d54s1
(B) m = - l to + l through zero.
(C) 47Ag : 1s22s22p63s23p64s23d104p65s14d10.
Since only one unpaired electron is present.
∴ 23 electrons have spin of one type and 24 of the opposite type.
(B) m = - l to + l through zero.
(C) 47Ag : 1s22s22p63s23p64s23d104p65s14d10.
Since only one unpaired electron is present.
∴ 23 electrons have spin of one type and 24 of the opposite type.
