Examples:
- Sr, Li as carbonates
- Na, Cs, K, Rb as nitrates
- Ca, Ba, Cu as chlorides
- powdered metals as Ti, Al, Be, Mg, Fe
etc.
Copper and strontium are two metals commonly used in fireworks that undergo a chemical change when they are heated, producing characteristic colors in the process. For example, copper compounds can create blue colors, while strontium compounds can produce red colors when ignited during a fireworks display.
Magnesium

The answer is MAGNESIUM!

Barium and Strontium are both used in medicines and to add colours to fireworks.
The metal commonly used in fireworks to create colorful sparks is a combination of various metal salts. When these metal salts are heated, they absorb energy and release it in the form of light, creating the vibrant colors we see in fireworks displays. Some common metals used in fireworks are strontium for red, barium for green, and copper for blue.
Fireworks that contain metals like strontium, barium, copper, and sodium can produce bright colors when burned. Strontium is an example of a metal used in fireworks that is less reactive than some other metals.
Magnesium is used both in making fireworks and medicines.
The answer is Potassium.
Alkali metals such as lithium, sodium, and potassium are typically used in fireworks to produce vibrant colors when they are heated due to their ability to emit characteristic light emissions.
Some common metals used to create different colors in fireworks are strontium (red), barium (green), copper (blue), and sodium (yellow). These metals are typically in the form of metallic salts or powders that emit specific wavelengths of light when burned. The combination of these metals with other chemicals produces the vibrant colors seen in fireworks displays.
