Calculate the energy, in electron volts, of a photon whose frequency is the following.

(a) 585 thz
(b) 3.50 ghz
(c) 40.0 mhz

planck's equation for the energy of a photon is e = hf, where f is the frequency and h is planck's constant. we use 1 ev = 1.60 ✕ 10−19 j for units of energy.

(a) for the energy of the photon at a frequency of 585 thz, we have e = hf

These models show the electron structures of two different nonmetal elements. which element is likely more reactive, and why? element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table. element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table. element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons. element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.
