Question

The electron moves to a higher energy level, the excited state when

• A. an electron loses energy
• B. an electron gains energy
• C. a proton loses energy
• D. a proton gains energy

Answer 1

The correct option is B an electron gains energy

The lowest energy state of the electron is known as the ground state. The electron moves to a higher energy level, the excited state when an electron gains energy. The electron loses the energy and comes back to its ground state. The energy emitted by the electron is seen in the form of electromagnetic energy.
