Did You Know that There Are Metals that Float and Explode On Water?

There are six alkali metals : Lithium ( Li ) , atomic number 11 ( Na ) , potassium ( K ) , rubidium ( Rb ) , caesium ( Cs ) and francium ( Fr ) . You ’re probably familiar with lithium , since it ’s inside the batteries of all your electronic gadget .

But did you know that you could cut a occlusion of it with a simple knife and that it floats on water while it boo H out ? And that cesium just explodes when you throw it into urine ?

I did n’t , plausibly because I skim that interpersonal chemistry class . Or perchance I did n’t skip it but I forgot about that school twelvemonth completely . In any case , I ’m a mark for demonstration videos in which things break loose while being explained by British teller .
