A spectroscope measures the light energy given off by ____ ?

Question

A) nuclear electrons

B) protons

C) neutrons

D) the nucleus

E) orbital electrons

Answer 1

Depends on the type of spectroscope. commonly, a uv-vis or IR spectrometer measures energy of orbital electrons (light energy). An NMR (nuclear magnetic resonance) measures nuclear environments, and a mass spectrometer measures the ratio of charge to mass (e/m). But E. would be your answer; light is the clue, since it pertains to the electromagnetic spectrum, which measures the energy of absorption or emission of electrons that are excited and/or returning to their ground state (these would be the outermost electrons, i.e., the orbital electrons).

Answer 2

E
