      Hello! Sodium makes fireworks yellow. It is a very reactive metal when it is just sodium by itself, and when it burns it produces a bright yellow colour. It is also a part of salt that you put on chips, combined with chlorine (sodium chloride), which makes it a lot more stable thankfully (putting sodium on your chips would be a very bad idea!). Also, if you have street lamps outside your house- the reason they are yellow is because the bulb has sodium in it.

      I do not know what you are trying to ask. May be it is about salts? Some elements will change the colour of flames and sodium would give you a yellow flame if I remember correctly.
