The greater the value of the principal quantum number 'n', the distance of an electron from the nucleus will be _.
Correct answer: B. Greater
- A. Lower
- B. Greater
- C. Higher
- D. Moderate
Explanation
The greater the value of the principal quantum number 'n', the greater the distance of an electron from the nucleus will be.The principal quantum number (n) determines the energy level of an electron. The higher the value of n, the farther the electron is from the nucleus. This is because the energy levels are arranged in shells, with each shell further from the nucleus than the previous shell.For example, an electron in the n=1 shell is closest to the nucleus, while an electron in the n=4 shell is furthest from the nucleus.

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.
