Elucidation of the structure of the periodic table The number of electron shells an atom determines the atomic period. Each skin has a subshell, which is loaded according to the following sequence, along with increasing atomic number: 1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p 7s 5f 6d 8s 5g 6f 7d 7P 8p

Photons are emitted when an electron in some atom moves from a higher energy state to a lower energy state. The photon has a wavelength which is exactly equal to the energy difference between the two states. The energy of a photon is equal to Planck's constant ( h) times its frequency (f)of
Ephoton = hf
