Which of the following reactions is accompanied by the first ionization energy of an element X?
X +(aq) → X 2+ (aq) + e-
X - (g) → X(g) + e-
X+ (g) → X2+ +e-
X (g) → X+ (g) +e-
X(s) → X + (g) + e-
Correct answer is D
ionization energy (IE) is the minimum energy required to remove an isolated gaseous atom's most loosely bound electron. The first ionization energy is quantitatively expressed as
X(g)+energy⟶X+(g)+e−
where X is any atom or molecule, X+ is the resultant ion when an electron( e−) was removed from the original atom.
