` (n+l)` value for the differentiating electron of copper atom is

The correct set of quantum number for the unpaired electron of chlorine atom is {:(n,l,m_(1)):} " " {:(n,l,m_(1)):}

The correct set of quantum numbers (n, l and m) respectively of the unpaired electron of chloine atom is

The correct electronic configuration of copper atom is:

The quantum numbers for the outer electrons of an atom are given by n = 2, l = 0, m = 0, s = +1//2

Assume that each of copper atom has one free electron. Estimate the number of free electrons in 1 mg of copper. Given that atomic weight of copper =63.5 and Avogadro number =6.02xx10^(23) . What is the charge possessed by these free electrons?

Values of the four quantum numbers for the last electron in the atom are n=4, l=1, m=+1 and s=-1/2. Atomic number of the atom will be

Find the difference in the value of (n+l) for 19^(th) electron of Cr and 21^(st) electron Sc.
