Which one of the following about an electron occupying the 1s-orbital in a hydrogen atom is incorrect?

Question

Canvas Classes · Accepted Answer

For 1s orbital in H:

(a) Correct — electron can be found at any distance (wavefunction non-zero everywhere)

(b) Correct — Virial theorem:  for Coulombic systems

(c) Correct —  is maximum at  for 1s orbital

(d) Incorrect — Total energy is constant (quantized), not a function of position. The electron's total energy is  eV regardless of where it is found. The most probable distance is , but total energy doesn't vary with position in quantum mechanics.

Answer: Option (d)
