How many valence electrons does calcium(Ca) have?
WebNov 26, 2024 · Electron affinities are more difficult to measure than ionization energies. An atom of Calcium in the gas phase, for example, gives off energy when it gains an electron to form an ion of Calcium. Ca + e – → Ca – – ∆H = Affinity = 2.37 kJ/mol. Electron affinity is one of the most important parameters that guide chemical reactivity.
