What is the relationship between the first ionization enthalpy and the reactivity of alkali metals?

Options

  1. AHigher ionization enthalpy corresponds to higher reactivity.
  2. BHigher ionization enthalpy corresponds to lower reactivity.
  3. CThere is no relationship between ionization enthalpy and reactivity.
  4. DIt depends on the specific alkali metal.

Correct answer

B. Higher ionization enthalpy corresponds to lower reactivity.

Step-by-step solution

Minima in ionization enthalpies occur at alkali metals, which are highly reactive.
