Reactivity of Metals Made by: Mais Al-reem Hammoud 8B
Does the reactivity of metals has a relationship with when it was discovered? • In this Presentation I will try and discover “if the reactivity of the metal has a relationship with when it was discovered?” • I think that there is a relationship between the reactivity of the metal and when it was found.
Gold Gold is not a very reactive metal. Its symbol is AU for a Latin word Aurum, which means gold . The atomic number of Gold is 79. This metal was discovered in Egypt by Middle East people, in 6000 BC.
sodium Sodium is a very reactive metal, it is almost at the top of the reactivity series. It’s symbol is Na for Natrium, which is a Latin word that means Sodium. Its atomic number is 11. It is a member of the alkali metals and is within group 1. It was found by Sir Humphry Davy in 1807.
Potassium Potassium is a really reactive metal, and is on the top of the reactivity series. Its symbol is K for Kalium in Latin. Its atomic number is 19. It was discovered in 1807 by Sir Humphry Davy.
Relationship So you see, there is a relationship between the time the metal was discovered and the reactivity of it. See, gold was discovered in 6000 BC, while Sodium was discovered in 1807. Sodium is way more reactive than gold.
Conclusion There is a relationship between the time the metal was discovered and its reactivity. All the metals that are discovered a long time ago is not reactive more than the new one because
