___________ __________ is the lowest energy level an electron will occupy in an atom at an ordinary condition

• ground state

• excited state

• highest state

• none of the above

When an electron absorbs enough energy, it jumps up to a higher level. This is called

• absorption state

• excitation state

• emission state

• relaxation state

According to Bohr, the energy absorbed by an electron upon excitation comes in a fixed amount called

• exact energy

• fixed energy

• quantized energy

• None of the above

Soon after the electron absorbs energy, this energy is released in a form of light or photon. True or False?

• True

• False
