Which of the following is the CORRECT statement about ^2 ?

Options

  1. A^2 represents atomic orbit
  2. BProbability density of the electron at that point
  3. C^2 0 for nodes
  4. D^2 has no physical meaning

Correct answer

B. Probability density of the electron at that point

Step-by-step solution

represents the wave function of an electron, which has no physical significance. ^2 represents the probability density of finding the electron at a given point in space. For nodes, the probability of finding an electron is zero, so ^2 = 0 . Therefore, ^2 represents the probability density of the electron at that point. Answer: Probability density of the electron at that point
