Lonization Energy decreases as you go down a family (group or column). Explain why this pattern occurs with force of attraction and atomic structure.

What type of electromagnetic radiation has a shorter wavelength than blue light

If you chip a tooth, most likely you will go to the dentist to have the missing material filled in. currently the material used to fill in teeth is a polymer that is flexible when put in, yet is hardened to the strength of a tooth after irradiation with blue light at a wavelength of 461 nm. what is the energy in joules for a photon of light at this wavelength?
