Which of the following orbital receives electron the latest?
Correct answer: C. 3d
- A. 4s
- B. 2s
- C. 3d
- D. 3p
Explanation
According to the Auf bau principle,latest electron goes to the the highest energy orbital.The increasing energy order for the orbitals given in the options is:2s<3p<4s<3dsince 3d has the highest energy so the latest electron goes into 3d.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
