Atomic radius of copper atom (r)= 128 pm
volume of sphere = 4/3 * pi * r^3 = 4/3 * 3.14 * 128^3
volume = 8780076.373 pm^3
The electron would absorb a quantum of energy
Also, remember, light energy (from the sun) is a reactant for photosynthesis. The plant uses water sunlight and carbon dioxide to make sugars as well as oxygen. Plants, the organisms that carry out photosynthesis, are typically the first ate organism is a Food chain and so most other organisms energy came from the plant somehow. But the plant got its energy from the sun.
