Question

(1). Represent the orbital with quantum numbers
N=3 and 1=1
(2). Give the mathematical expression that shows the dual behaviour of material particles .


(3) the general electronic confirguration of 'd' block element is ..............

Answer 1

(1) The spin of one electron must be +1/2 while the spin of the other electron must be -1/2. There are three subshells in principal quantum level n=3. Since l=3 refers to the f subshell, the type of orbital represented is 4f.

(2) mv²=hv/ wavelength. Or wavelength= h/ mv²

(3) Generally the electronic configuration of these elements is (n-1)d1–10 ns1–2. The (n–1) stands for the inner d orbitals which may have one to ten electrons and the outermost ns orbital may have one or two electrons.

Hope it helps you....
