Did you know that the youngest Nobel Laureate was William Bragg who won a Nobel prize in Physics at age 25? This was in 1915.
One of the discoveries William and his father made "showed that crystals of such substances as Sodium Chloride (NaCl or common salt) contain no actual molecules of NaCl, but simply Sodium ion and Chloride ion arranged in geometric regularity. This discovery revolutionised theoretical chemistry."
