What causes the lines in the spectrum for elements? a quantum absorption of energy as various electrons are excited to a higher energy level a quantum release of energy as electrons drop back to their ground state none of the above a continuous release of energy from the heated element

The lines in the spectrum for elements are caused by:<br /><br />a quantum release of energy as electrons drop back to their ground state<br /><br />When electrons in an atom absorb energy, they become excited and move to higher energy levels. As they return to their lower energy levels or ground state, they release energy in the form of light. This release of energy at specific wavelengths results in the emission lines observed in the spectrum of elements.
