URGENT Explain in 1 - 2 sentences how emission and absorption spectra can support the theory that electron orbitals are arranged in discrete energy levels.

Each line in the emission spectrum corresponds to a specific amount of energy. This energy is emitted when electrons from higher-energy electron shells transition to a lower-energy shell. ... This is evidence that electrons are found in shells with discrete energy levels .

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
