What is responsible for the colors emitted by elements?

Heating an atom excites its electrons and they jump to higher energy levels. When the electrons return to lower energy levels, they emit energy in the form of light. Every element has a different number of electrons and a different set of energy levels. Thus, each element emits its own set of colours.

Why do certain elements burn different colors?

When heated, the electrons get excited and move to a different orbit and as they cool down they move back to their normal orbit and this extra energy produces light waves. Each element has different amounts of extra energy, producing different colors.

What can you conclude about the elements and the color of flame produce?

Because each element has an exactly defined line emission spectrum, scientists are able to identify them by the color of flame they produce. For example, copper produces a blue flame, lithium and strontium a red flame, calcium an orange flame, sodium a yellow flame, and barium a green flame.

Why do elements emit colors when heated?

Heating an atom excites its electrons and they jump to higher energy levels. When the electrons return to lower energy levels, they emit energy in the form of light. The colour of the light depends on the difference in energy between the two levels.

Why do metals have different colors of light?

At this point, there is light being emitted which produces different colors. Metals are made up of different elements so when these elements react with heat, light is emitted. To understand this better, let’s take a look first at the properties of metals.

How does burning affect the color of light?

Some chemicals only work in certain form of burning. Some work by sprinkle it onto the fire, apply it to the woods, while the other work by making a candle out of it. The different form of burning will affect how stable the color of the light will be.

What happens to metals when they react with heat?

At this point, there is light being emitted which produces different colors. Metals are made up of different elements so when these elements react with heat, light is emitted.
