l Questions: (Total points 20) D-1 Light\’s Relationship to Matter: ow we can relate the existence of any color to electrons being on different level of energy? (6 points) D-2 Electron Configurations: Describe electron configuration theory. How we would be able to use both the ground state and diagram configuration to present valance and core electrons for sodium and calcium atoms. (8 points)

Solution

1. Electrons of an atoms have different level of energy depending upon the distance of their orbital from the nucleus. Electrons can get excited to higher energy levels farther from nucleus and when they fall back to lower energy they emit radiation in the form of quanta (photon). ████ █████ █████ ████████████ ███ ██████████████████████ █████ ███████████████ ████ ██████████ ██████████████████████ ███ █████████████ ██████████████████████ ███████, ████████████████ ████████ ████████████ ████ ████████ ███████████████████ █████████████████ █████████ █████ ██████ ████ ████████████████ ████ ████████ ███████████████ ████████████ █████████ ███████████ ████████████ ██████████ █████ ██ ██████████████ ██████████████████ ████ ████████████████ █████████ █████████████ ███████████ ███ █████████████████
