Formula and explanation
Formula: A (g) ightarrow A⁺ (g) + e⁻ Δ H = I₁, where I₁ is the first ionization energy. Applicable Conditions: The process of a gaseous atom losing an electron to form a gaseous cation. Brief Explanation: Ionization energy measures the ease with which an atom loses an electron. The first ionization energy I₁ is usually positive (endothermic process). Its magnitude is influenced by atomic radius, effective nuclear charge, and electron configuration, showing periodic trends across the periodic table.
