Regardless of how hot the flame is, when a metal ion is placed in a flame, it always give off the same color light. Why?

• 
  The number of protons is still the same, so the same number of electrons get excited and fall back to the ground state the same way and give off the same color every time.

• 
  The number of electrons is still the same, so the same number of electrons get excited and fall back to the ground state the same way and give off the same color every time.

• 
  The number of neutrons is still the same, so the same number of electrons get excited and fall back to the ground state the same way and give off the same color every time.

• 
  The number of ions is still the same, so the same number of electrons get excited and fall back to the ground state the same way and give off the same color every time.
