The correct representation for 'd' orbital is:
Correct answer: C. (n-1)d1-10ns1-2
- A. (n-1)d1-9ns1
- B. (n-1)d1-5
- C. (n-1)d1-10ns1-2
- D. (n-1)d1-10ns2
Explanation
d block elements have a general electronic configuration of (n-1)d 1-10ns1-2. These elements can find stability in half-filled orbitals as well as fully filled d orbitals. An example of this is the electronic configuration of chromium, which has half-filled d and s orbitals in its configuration: [Ar]3d54s1.

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.
