Reactivity of polonium
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. WebTrace quantities of polonium hydride may be prepared by reacting hydrochloric acid with polonium-plated magnesium foil. In addition, the diffusion of trace quantities of polonium in palladium or platinum that is saturated with hydrogen (see palladium hydride) may be due to the formation and migration of polonium hydride.
