Which of these has max. electrons in its 3d subshell?
Correct answer: C. Ni+2
- A. Sc+3
- B. Ti+4
- C. Ni+2
- D. Fe+2
Explanation
Electronic configuration of Ni+2 is :1s2,2s2,2p6,3s2,3p6,3d8.It has 8 electrons in 3d subshell which is highest among all the other options,hence it is the correct option.

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.
