Electron shell diagram for radium.
Thomas Savery was an English engineer and inventor of an early form of steam engine (patented 1698), used for pumping water out of mines. His patent covered Thomas Newcomen's later invention (c.1712), and for this reason the two entered partnership for the development of Newcomen's engine. Savery also developed an early form of paddle-driven boat.
