Quantum numbers are always in the order n,l,ml, ms. Which of the following quantum numbers is likely NOT to occur and why?
A. 0,2,3,4 because the principal quantum number belongs to natural numbers
B. 2,1,-2,+1/2 because the spin quantum number ranges from -l to l
C. 3,2,1,-1/2/ beacuse the magnetic quantum number is always negative
D.4,3,-4,+-1/2 because the azimuthal quantum number is always a fraction.
The electronic configuration of an atom's valence shell is ns2np2. During the titration of a CuCl2 with conc. H2SO4(0.1M) acid and a suitable indicator was used such that PH(y) of the HCl was 1.500. What is the period to which the element belongs with respect to the fact that y= -log(10+10n/2)
