Atoms don’t absorb all wavelengths of light because of… a. Their valence electrons
b. Their shells
c. Their color
d. They do absorb all wavelengths of light

b. Their shells

Explanation:

The electronic shell of atoms represents the energy levels in a particular atom.

To understand the way atoms absorb energy, we must know that the wavelength absorbed is commensurate with the energy of the atom. This available energy allows for specific amount of energy to be absorbed.

Therefore, the electronic shell in an atom determines the absorption wavelength of the atom.
