A

Higher ionization potential generally leads to lower reactivity.

B

Lower ionization potential indicates more stable ions.

C

Ionization potential has no effect on reactivity.

D

Elements with higher ionization potential are more likely to lose electrons.

Understanding the Answer

Let's break down why this is correct

Answer

The ionization potential is the energy needed to remove an electron from an atom, and it tells us how easily an atom can lose that electron. When the ionization potential is low, the atom can give up an electron easily, so it tends to react quickly, especially with elements that want electrons, like halogens. Conversely, a high ionization potential means the atom holds onto its electrons tightly, making it less reactive. For example, sodium has a low ionization potential, so it readily loses an electron and reacts violently with water, while chlorine has a high ionization potential but needs an electron, so it reacts strongly with metals that can donate electrons. Thus, ionization potential helps predict which elements will be more reactive in chemical reactions.

Detailed Explanation

When an element has a high ionization potential, it needs more energy to remove an electron. Other options are incorrect because Lower ionization potential means an electron is easier to remove, not that the resulting ion is more stable; Ionization potential is a key factor in predicting how readily an element will react.
