Groups of the periodic table - ReachSupportNetwork.eu A heat engine operating in outer space may be assumed equivalent to a Carnot engine operating between reservoirs at temperatures $T_H$ and $T_C.$ The only way heat can be discarded from the engine is by radiation, the rate of which is given (approximately) by: $\left|\dot{Q}_{C}\right|=k A T_{C}^{4}$ where k is a constant and A is the area of the radiator. The total number of these subatomic particles held by the respective elements are responsible for their unique properties (including radioactivity). Form ions with a charge of usually +2 but can varyusually 2 valence electrons.
