 The name of my element is rubidium.
 Its atomic number is 37 and its symbol is [Rb].
 The origin of its name is derived from the Latin word
rubidus which means “a deep red”.

 The group is 1
 The period is 5
 It only has 1 valence electron
When was rubidium
discovered/produced
 Rubidium was discovered in 1861
 It was produced when they burned lepidolite wich contains little amounts
of rubidium
Who discovered/produced rubidium
 The 2 people who discovered rubidium are gustav kirchhoff and robert
bunsen
 There isnt a definitive anwser but some minerals contain rubidium and they
extract it these minerals are alkarb and caesium
Where it can currently be made/found
 It can be found in these minerals lepidolites, biotites, feldspar, carnallite and
caeseum
 I couldn’t find a way to make it
4 physical descriptions
 It is a soft,silverywhite metal that is a solid at room temperature
5 uses for rubidium
 It is used in fireworks to give a purple color
 It is used as a getter in vacuums
 It is used to manufacture photocells
 It is also used to manufacture a special glass
 It can also be used as a propellant in ion engines on a spacecraft
