    The classical Rutherford model fails because orbiting electrons, according to electromagnetic theory, should continuously emit radiation, lose energy, and spiral into the nucleus. This instability cannot explain atomic stability or discrete spectral lines observed in atomic emission, contradicting experimental results.

  2. Ionization energy is the energy required to remove the outermost electron from an atom in its ground state to infinity. For a hydrogen atom, its ionization energy is 13.6eV (electron volts) or 2.18 × 10⁻¹⁸ J. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/chapterRead more

  3. Bohr’s quantization condition states that the angular momentum of an electron in a stationary orbit is quantized and given by mvr = nℏ, where m is mass, v is velocity, r is radius, and n is an integer.
