Step-by-Step Analysis

The question asks which statements are true for multi-electron atoms and specifies that multiple selections may be correct. Option 1: The Bohr model describes the electron energies. This is not accurate for multi-electron atoms. The Bohr model works well only for hydrogen-like systems with a single electron; it does not account for electron-electron repulsion and screening effects that are crucial in atoms with more than one el......Login to view full explanation
