Which of the following statements correctly describe the significance of the wave function () and pr — Atomic Structure Chemistry Question

💡 Solution & Explanation

$\psi$ is a mathematical function representing wave amplitude with no direct physical meaning. $\psi^2$ is the probability density, measuring the likelihood of finding an electron in a unit volume. A region where $\psi^2 = 0$ is a node. However, for a $1s$ orbital, $\psi^2$ is maximum at the nucleus, not zero.
