In a flame test, atomic-level changes in electron energy create macroscopic-level changes in visible light energy. Which statement about flame tests is true?(1 point)

A.Visible red light corresponds to relatively large changes in the energy levels of the electrons.
B.Because the energy levels of the electrons in different metals are usually not the same, different metals usually emit different colors of visible light.
C.Because the energy levels of the electrons in different metals are usually the same, different metals usually emit the same colors of visible light.
D.Visible blue light corresponds to relatively small changes in the energy levels of the electrons.

B) because the energy levels of the electrons in different metals are usually not the same, different metals usually emit different colors of visible light.

Explanation:

Answers to the rest:

1. B) macroscopic outputs.

2.A) a microscopic change creating a macroscopic output

3.B) Because the energy levels of the electrons in different metals are usually not the same, different metals usually emit different colors of visible light.

4.A) Heat is applied to a solid, causing its molecules to move quickly.

5.A) strontium, sodium, copper, potassium

The energy levels of the electrons in different metals are usually not the same, different metals usually emit different colors of visible light.

A flame test is a type of test in which energy is supplied to an atom such electrons move form a lower to a higher energy level. The electrons return to ground state an emit a photon of energy which appears as visible light.

Hence, the energy levels of the electrons in different metals are usually not the same, different metals usually emit different colors of visible light.
