  2. Absorption spectrum forms when atoms or molecules are excited from lower energy level to higher energy levels.

  3. Emission spectrum forms when atoms or molecules are de-excited from higher energy level to lower energy level.

  4. Line spectra are also known as molecular spectra.

  5. Band spectrum forms due to the vibrations and rotations of atoms in molecules.

D Correct answer
Explanation

Line spectra are also called atomic spectra because the lines represent wavelengths radiated from atoms when electrons change from one energy level to another.  Band spectra are also known as molecular spectra because they are produced when the emitting substance is in the molecular state.
