JEE Main Chemistry question
Statement 1: Only the principal quantum number determines the energy of an electron in an orbital in a sodium atom. Statement 2: For a one-electron system, the expression for energy is the same as that obtained in Bohr's theory.
Answer: (D)
Solution
Sodium is a multi-electron atom, where orbital energy depends on both and (due to shielding/penetration), not on alone — so the Assertion is false. Statement 2
