  1. Question 1

    Q1. The energy of the nth orbit in hydrogen-like atom is

    • A) -13.6 Z / n eV
    • B) -13.6 Z² / n² eV
    • C) -13.6 n² / Z² eV
    • D) -13.6 n / Z eV

    Answer: -13.6 Z² / n² eV

    Explanation: Using Bohr's model for hydrogen-like atoms, energy is proportional to Z² and inversely proportional to n².
