When examining Bohr diagram, the energy level with the greatest amount of energy is the one

• farthest from the nucleus

• closest to the nucleus

• they all have the same energy levels

Absorption of energy by an electron results in 

• it moving from the ground to an excited state
• it moving from an excited to the ground state
• the emission of a photon
• it moving from an excited to the ground state and the emission of a photon

How do electrons become excited?

• Emitting light/energy

• Absorbing light/energy

• Going down an orbital/energy level

• Going up an orbital/energy level

What form of energy is emitted when an excited electron returns to the ground state?

• Photon (light)

• Heat

• Kinetic

• Potential
