Please answer the following questions, thanks.
Which of the following statements about electronic configurations of atoms and mononuclear
ions, and atomic orbital quantum numbers, are true or false false The secondary (angular
momentum) quantum number is always an odd number. true The electronic configuration of Cl
is [Ne]3s23p6, false ? The value of m, is always equal to n minus 1 true V4+ has the same
electronic configuration as K. false The valence electronic configuration of chlorine is 3s23p3
Solution
False The secondry ( angular momentum) quantum number is always an odd number
l = 0, 1 ,2, 3 to n-1
False The electronic configuration of Cl^- is [Ne]3s^23p^6
Cl = 17 [Ne]3s^2 3p^5
False The value of ml is always equal to n minus l.
ml values -l to +1 including 0
True V^4+ has the same electronic configuration as K
V^4+Â Â = [Ar]4s^1
KÂ Â Â =19 [Ar]4s^1
False The valence electronic configuration of chlorine is 3s^2 3p^3
Cl = 17Â Â [Ne]3s^2 3p^5
