Using the ionization energy for sodium (495 kJ/mole), would a photon with a wavelength of 23.7 nm be able to transfer enough energy to the valence electron in a sodium atom to cause it to ionize if all of the energy of the photon is transferred to the 3s1 electron of the sodium atom? What would be the maximum kinetic energy of the ejected electron?.

gas

explanation:

smoke is the matter of a gas

c. electrical charges of ionic bonds.

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
