Question

the modern atomic theory quiz complete 1 2 orbit electron what happens when the electron moves from the first energy level to the second energy level? energy is absorbed, and an emission line is produced. energy is released, and an emission line is produced. energy is absorbed by the atom. energy is lost from the atom.

Explanation:

When an electron moves from a lower (first) to a higher (second) energy level, it needs to gain energy. This energy is absorbed by the atom. Emission lines are produced when electrons move from higher to lower energy levels, releasing energy.

Answer:

Energy is absorbed by the atom.
