Calculate the energy of quantum of radiant energy with a frequency of 5.00 x 10^11/s. show your work.

Calculate the energy of quantum of radiant energy with a frequency of 5.00 x 10^11/s. this can be solved using Planck-Einstein Equation

E = hf

Also known as Planck's Relation, the energy of a photon is given by:

 , where:

E = Energy (J)

h = Planck's Constant (J*s) = 6.626070040×10−34 Js

f = Frequency (Hz) = 5.00 x 10^11/s

E= 3.31x10^-22 j

what does the table look like

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
