Question

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 energy level (first energy level) to a higher energy level (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). Since the electron is moving to a higher level here, no emission line is produced. Also, energy is not lost from the atom in this upward transition.

Answer:

Energy is absorbed by the atom.
