Answer

  1. Electromagnetic Waves Theory: Energy is radiated or absorbed continuously.

Planck's Quantum Theory: Energy is radiated or absorbed not continuously but discontinuously in the form of small packets called quantas or photons.

  1. Hund's rule is being violated: Because orbitals having equal energy should be singly filled first and then pairing of electron should take place.
