Question

Designations of some orbitals are given below. Arrange the orbitals with possible designations in the order in which they are filled with electrons $6s,8p,7s,4d,2p,3d,3f,4f$.

• A. $2p<3d<4d<4p<6s<8p<7s<4f$
• B. $2p<3d<4p<4d<6s<4f<7s<8p$
• C. $3d<2p<4p<4d<6s<4f<7s<8p$
• D. $2p<3d<4p<4d<4f<6s<7s<8p$

Answer 1

Answer: (B)

$2p<3d<4p<4d<6s<4f<7s<8p$

The orbitals with possible designations in the order in which they are filled with electrons is $2p<3d<4p<4d<6s<4f<7s<8p$.
