WebNov 1, 2024 · Beginning in the late 1950s, the U.S. met this challenge by developing nuclear batteries known as radioisotope thermoelectric generators (RTGs) and producing plutonium-238 (Pu-238) as their fuel, enabling the exploration of deep space. WebNov 26, 2024 · Electron affinities are more difficult to measure than ionization energies. An atom of Polonium in the gas phase, for example, gives off energy when it gains an electron to form an ion of Polonium. Po + e – → Po – – ∆H = Affinity = 183.3 kJ/mol. Electron affinity is one of the most important parameters that guide chemical reactivity.
