Answer:
C. protons + neutrons
Explanation:
The mass number is defined as the total number of protons and neutrons in an atom.
Photon
energy is the energy carried by a single photon with a certain wavelength and
frequency. These terms are related by an equation. <span>
E = hv
where h is the Planck's constant (6.626 x
10-34 J s), v is the frequency.</span>
We calculate the energy as follows:
E = hv
E = 6.626 x 10-34 J s ( 7.31 × 10^14 / s ) = 4.84 x 10^-19 J
