  1. Question 1

    Q1. What is the main reason for the presence of spectral lines in the atomic emission spectrum?

    • A) The presence of a continuous energy distribution
    • B) The quantization of energy levels in the atom
    • C) The random motion of electrons
    • D) The absence of energy absorption

    Answer: The quantization of energy levels in the atom

    Explanation: The main reason for the presence of spectral lines in the atomic emission spectrum is the quantization of energy levels in the atom, resulting in specific energy transitions.
