Question

What will happen when an electron jumps from an excited energy state to a more stable energy state in a hydrogen atom?

• A. Electromagnetic radiation is emitted by the atom
• B. Electromagnetic radiation is absorbed by the atom
• C. The atom becomes a positively charged ion
• D. The atom becomes a negatively charged ion
• E. The atom undergoes nuclear decay

Answer 1

The correct option is A Electromagnetic radiation is emitted by the atom

When an electron jumps from an excited energy state to a more stable energy state in a hydrogen atom, electromagnetic radiation is emitted by the atom. The energy of the electromagnetic radiation emitted is equal to the difference in the energy of the excited state and the energy of more stable state.
