Introduction

Ionization is a fundamental concept in chemistry that involves the removal of an electron from an atom, resulting in the formation of an ion. Potassium (K) is a highly reactive metal that readily loses an electron to form a positively charged ion, known as a cation. In this article, we will explore the correct equation that represents the ionization of potassium.

Understanding Ionization

Ionization is a process in which an atom or molecule gains or loses electrons, resulting in the formation of ions. When an atom loses an electron, it becomes a positively charged ion, known as a cation. Conversely, when an atom gains an electron, it becomes a negatively charged ion, known as an anion. The ionization of potassium involves the loss of an electron from the neutral potassium atom, resulting in the formation of a positively charged potassium ion.

The Ionization Process

The ionization process of potassium can be represented by the following equation:

K+energy→K++e−K + \text{energy} \rightarrow K^{+} + e^{-}

In this equation, the neutral potassium atom (K) absorbs energy, which is sufficient to remove an electron from the atom. The resulting positively charged potassium ion (K+) is formed, along with the free electron (e-). This equation represents the correct process of ionization, where the potassium atom loses an electron to form a positively charged ion.

Comparing the Options

Let's compare the given options to determine which one correctly represents the ionization of potassium.

Option A

K+energy→K++e−K + \text{energy} \rightarrow K^{+} + e^{-}

This equation correctly represents the ionization of potassium, as it shows the neutral potassium atom (K) absorbing energy and losing an electron to form a positively charged potassium ion (K+).

Option B

K+e−+energy→K−K + e^{-} + \text{energy} \rightarrow K^{-}

This equation is incorrect, as it shows the neutral potassium atom (K) gaining an electron (e-) and energy, resulting in the formation of a negatively charged potassium ion (K-). This is the opposite of ionization, where the atom gains an electron to form a negatively charged ion.

Option C

K++e−→K+energyK^{+} + e^{-} \rightarrow K + \text{energy}

This equation is also incorrect, as it shows the positively charged potassium ion (K+) gaining an electron (e-) and releasing energy, resulting in the formation of a neutral potassium atom (K). This is the opposite of ionization, where the atom loses an electron to form a positively charged ion.

Conclusion

In conclusion, the correct equation that represents the ionization of potassium is:

K+energy→K++e−K + \text{energy} \rightarrow K^{+} + e^{-}

This equation shows the neutral potassium atom (K) absorbing energy and losing an electron to form a positively charged potassium ion (K+). The other options are incorrect, as they either show the atom gaining an electron or the positively charged ion gaining an electron.
