Based on the data from the Flame Test Lab, which metal ion has the LOWEST FREQUENCY?

• potassium

• sodium

• copper

• strontium

The chemicals were mislabeled in the lab. So a student performs a flame test on an unknown metallic salt solution. The flame turns a light violet color. Based on this observation, what is the most likely identity of the metal?

• potassium

• calcium

• lithium

• barium
