Solution
Both Statement I and Statement II are correct.
Explanation:
Statement I is correct, as in a neutral atom, the quantity of protons is equivalent to the quantity of electrons, thus balancing the charges and rendering the atom electrically neutral.
Statement II is accurate when electrons in atoms shift between distinct energy states, emitting or absorbing electromagnetic radiation at certain wavelengths, hence producing a unique spectral line pattern for each element. This is referred to as an atomic spectrum.
