Question

Which of the following combinations of quantum numbers are allowed? Select all that apply. n = 5, 1 = 3. mi = 3, ms = -1/2 n = 2,l = 2, mi = 2,ms = +1/2 n = 3, l = 1. mi = -2, ms = +1/2 n = 5,1 = 2, mi = -1, ms = +1/2 Which of the highlighted elements in the figure has the greatest number of unpaired electrons per atom? Write the electron configurations of the following species. Use the orbital diagram tool to add the orbital's, click on the orbital's to add the electrons. Make sure you add electrons according to Hund's rule. Which of the following species are isoelectronic with Ne? Check all that apply.

Explanation / Answer

1)
a) n= 5, l=3 , ml= -3 , ms = -1/2

d) n= 5 , l = 2, ml= -1 , ms = +1/2

the above are allowed quantum numbers

2) red coloed element more no.of un paired electrons

3) isoelectronic with Ne are Mg+2, F- , Na+ ,Al+3

4)C = 1s^2 2s^2 2p^2
S = 1s^2 2s^2 2p^6 3s^2 3p^4
Ti = 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^2
Ti+4 = 1s^2 2s^2 2p^6 3s^2 3p^6
