Put salt (aka sodium chloride) in your pasta water and you’ll end up with delicious spaghetti. Put pure sodium in it instead… and it will explode.
It’s the latest edition of “The Element of Surprise,” our occasional series about the hidden stories behind the periodic table’s most unassuming atoms, isotopes, and molecules. This time we’re talking all about sodium.
It’s the periodic table’s saltiest element. It powers your body like a battery and you need it to survive. So why is too much of it bad for you? Plus, how did salt help the North win the Civil War?
