can u help me with this?

Question

If the principal quantum number n=6, the correct sequence of filling of electrons will be?

 

a. ns - np - (n-1)d - (n-2)f

b. ns - (n-2)f - (n-1)d - np

c. ns - (n-1)d - (n-2)f - np

d. ns - (n-2)f - np - (n-1)d

 

Answer 1

If you look at the periodic table, you will up the electron orbitals in the following order.

 

6s → 4f → 5d → 6p
