Question

_________ is the colour of the flame when copper metal is burned on the flame ​

Answer 1

Answer:

When you burned the skewer tip coated with copper sulfate, you should have seen that the flame gained blue-green traces. This is because when the metal copper is burned, it makes bluish-green light. If an atom's electrons lose energy, they drop down to a lower energy level, and the lost energy can be released as light.
