Two sodium atoms are walking down the street. Suddenly one says “Oh, my God, I’ve lost an electron!” The other says “Lost an electron! Are you sure?” and the first replies “Yes, I’m positive!”
A small piece of sodium that lived in a test tube fell in love with a Bunsen burner. "Oh Bunsen, my flame," the sodium pined. "I melt whenever I see you," The Bunsen burner replied, "It's just a phase you're going through."
