Evaluate each statement:

(1) ✓ Correct — The total energy is maximum (least negative) at , the most probable radius.

(2) ✗ Incorrect — Actually, the electron CAN be found at . The wave function  is non-zero everywhere (no radial nodes for 1s), so there is a non-zero probability of finding the electron at any distance including . Wait — this statement says the electron CAN be found there, which is TRUE.

Let me reconsider: (1) says total energy is maximum at  — but total energy is constant (qua
