Flame Tests

Which type of ion causes the flame to change colour in a flame test?

• Metal

• Non metal

• All atoms do this

• Only crime scene atoms do this

A flame that is blue during a flame test means…

• The electron did a big jump

• The electron did a small jump

• There is not much energy released

• The wavelength is long

The colour of a flame during a flame test can help identify…

• The non-metal ion

• The metal ion

• The suspect in a crime

• The mood of the flame

A flame that turns red during a flame test means

• The wavelength is short

• There is lots of energy released

• The electron did a big jump

• The electron did a small jump

What is the primary reason different metals produce different colors in a flame test?

• The size of the metal atoms

• The number of protons in the nucleus

• The number of electrons and their arrangement

• The type of Bunsen burner used

Explain why the flame test is sometimes referred to as "firework colors."

• Because fireworks are made from paper and gunpowder

• Because the colors produced in the flame test are similar to those seen in fireworks

• Because fireworks are tested using flames

• Because the flame test is used to make fireworks

Describe the process that occurs when electrons are excited during a flame test.

• Electrons are absorbed by the nucleus

• Electrons move to a lower energy level

• Electrons jump to a higher energy level

• Electrons are ejected from the atom

How does the distance between electron shells affect the color observed in a flame test?

• It determines the brightness of the color

• It affects the wavelength of light emitted

• It changes the temperature of the flame

• It alters the shape of the flame

Why do different atoms have different flame colors?

• Because they have different numbers of neutrons

• Because they have different electron configurations

• Because they have different atomic masses

• Because they have different melting points

Plan an experiment to determine the metal present in an unknown sample using the flame test.

• Measure the mass of the sample

• Compare the flame color to known standards

• Dissolve the sample in water

• Use a magnet to test the sample
