all details about electronics
Ionisation: If the amount of external energy is large enough the valence electron can gain sufficient kinetic energy (energy of movement) to be removed completely from its atom
Dispersion of Light: When a beam of light is permitted to pass by a prism, it splits in a band of different colors. This band of different colors is known as spectrum and the p
