Fe is the chemical symbol for iron, atomic number 26. Sometimes the periodic table of elements seems like high school, full of cliques and gossip. Hydrogen and oxygen atoms spend lots of time hanging out together while elements like Argon and Radon are loners, never bonding with others. Gold, Au, and Silver, Ag, are the rich elements, but I honestly think iron the the most popular. I can't believe iron thinks "rusty" is a term of affection!
