MCQ
According to quantum mechanics, $|\psi|^2$ (r) the wave function squared gives:
  • A
    probability of finding an electron
  • probability density of finding an electron
  • C
    probability density of finding a proton
  • D
    probability of finding a neutron

Answer

Correct option: B.
probability density of finding an electron
(b) probability density of finding an electron
Explanation: The probability density of finding an electron at a point within an atom, predicts the region around the nucleus where the electron can most probably be found.
