An electron having highest energy in the set of quantum number is:
Correct answer: D. 5,0,0,1/2
- A. 3,2,2,1/2
- B. 4,1,0,1/2
- C. 2,2,-1/2
- D. 5,0,0,1/2
Explanation
In the context of the quantum numbers, the principal quantum number (n) indicates the energy level or shell of an electron in an atom. The higher the value of n, the higher the energy level. Therefore, the electron with the highest energy in a set of quantum numbers is the one with the highest principal quantum number (n). Hence, option D is correct among all the options because it has the highest value of principal quantum number.

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.
