B) all electrons have different amounts of intrinsic energy C) electrons have unique arrangements in energy levels, shells, and orbitals. D) electrostatic varies by element. Submit Atomic Theory and Periodic Law

Explanation / Answer

When you heat an atom, some of its electrons are "excited" to higher energy levels.

When an electron drops from one level to a lower energy level, it emits a quantum of energy.

The wavelength (colour) of the light depends on the difference in the two energy levels.

We can see only those transitions that correspond to a visible wavelength.

Hence option 'B' will be correct i.e all electrons have different amount of. Intrinsic energy.
