Chapter 3, Problem 5STP

Interpretation Introduction

Interpretation: Formation of an ion should be discussed.

Concept Introduction: Every matter is made of chemicals; the importance of chemistry is that it's the study of everything. Chemistry is all about how something interacts to affect the structure, composition, as well as knowing properties of substances.

Answer to Problem 5STP

Correct answer: The correct option is B.

Explanation of Solution

Reason for correct option:

Protons are defined as a positively charged $\left(+ve\right)$ sub-atomic particles/ units found in nucleus of an atom. Electron are negatively charged subatomic particles found orbiting nucleus of an atom. Neutrons are subatomic particles found in the nucleus of an atom which are neutral.

An ion is atom or group of atoms that has an electrical charge, either negative or positive. Ions are formed as atoms loose or gain electrons to achieve stability. An ion forms when an atom gains or losses electrons from its outer, or valence, shell.

Conclusion

Reasons for incorrect options:

Option A: An ion is simply a charged atom. So, this is an incorrect option.

Option C: An ion is simply a charged atom. So, this is an incorrect option.

Option D: An ion is simply a charged atom. So, this is an incorrect option.
