 The Three Elements Rubidium, Titanium and magnesium! The first element I am going to be talking about is rubidium! Its symbol is Rb. It was discovered by Robert Wilhelm Bunsen and Gustav Robert Kirchhoff. It was discovered 1861 Rubidium is highly reactive in water. It is a type of metal. That is a little bit of info for now! Rubidium is used in several things! The first thing is that it is in photo cells! I did not know that before, that is really cool! It is also used as a catalyst. It is also used in special glasses and since it is easily ionized, it might be used as a propellant in ion engines on spacecraft. Rubidium is used in vacuum tubes as a getter, a material that combines with and removes trace gases from vacuum tubes. That is what it’s in! There are still a few more facts left! On of them is that the atomic number, it is 37! The melting point is 38.89 degrees c, and the boiling point is 688.0 degrees c. its crystal structure is cubed, it sounds awesome! Did you know it’s obtained from lithium production? Well, you know now! It’s in the alkali metal group! Well, that was all about Rubidium! Ok, the next element is Titanium! It was discovered by William Gregor in 1791. Its symbol is Ti. It is unreactive in most acids! I hope you learn a lot from the rest! At first I did not know what titanium was, but now that I have seen what it is in and it’s interesting! One of the things it’s in is paint (did not know that!)! It’s also used in rubber and paper. That’s what titanium is in! These are some important facts about titanium! The atomic numero is 22. Its melting point is 1668 degrees c and the boiling point is 3287 degrees c! Titanium is as strong as steel! Thank you! As you probably know this next element is magnesium! It was discovered by Sir Humphry Davy in 1808! The symbol is Mg. I hope you enjoy! Magnesium is very light wait. It is malleable. It is a silvery white metal that burns in air with a white flame. It responds to water when the temperature elevates. That was some info, hope you learned! Magnesium is used for airplanes and missiles! That is sort of cool! Its atomic number is 12. Its melting point is 650 degrees c and the boiling point is 1090 degrees c. thanks again! I hope you learned a lot from my report and enjoyed!!!
