reducing agents. The different oxidizers in the firework make the
different colors people see in the sky.
Burning of metals in fireworks is a chemical reaction and is what
makes the fireworks glow with different colors.
The process that causes fireworks to emit light is the excitation of an electron. When you give energy to an electron is a substance via heat etc. it is able to move up to a higher energy level. There is a set amount of energy between the energy state the the electron was in and now is in. The elect…
