 * <span style="font-family: 'Times New Roman','serif'; font-size: 19px;">Unusual facts: the word //phosphorus// originates from 2 Greek words, //phos// and //phoros,// meaning “light” and “bearer**.”** White phosphorus was previously used as a weapon during the Korean and Vietnam wars, as either grenades or as airstrikes. And if the white phosphorus would get onto your skin, it would pretty much melt it, in which the only way to stop the burning is to sever the skin that has been touched by the white phosphorus.
