For an electron in K-shell, the correct four quantum numbers are represented by;
Correct answer: C. Option C
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
The correct four quantum numbers for an electron in the K-shell are: Principal quantum number (n) = 1 Azimuthal quantum number (l) = 0 Magnetic quantum number (m) = 0 Spin quantum number (s) = +1/2 or -1/2 The principal quantum number (n) determines the energy level and distance from the nucleus, and for the K-shell, it has a value of 1. The azimuthal quantum number (l) determines the shape of the electron's orbital, and for the K-shell, it has a value of 0, indicating that the electron is in an s orbital. The magnetic quantum number (m) specifies the orientation of the orbital in space, and for an s orbital, it can only have a value of 0. The spin quantum number (s) indicates the direction of the electron's spin, and it can have a value of +1/2 or -1/2.

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.
