Ion Formation Worksheet Answers and Solutions

Ion Formation: Understanding the Basics

Ion formation is a fundamental concept in chemistry that involves the gain or loss of electrons by atoms, resulting in the formation of ions. Ions are atoms or molecules that have acquired a net positive or negative charge due to the gain or loss of electrons. In this worksheet, we will explore the basics of ion formation and provide answers and solutions to common problems.

What is Ion Formation?

Ion formation occurs when an atom or molecule gains or loses electrons, resulting in a net positive or negative charge. This can happen through various means, such as:

• Electron gain: When an atom or molecule gains one or more electrons, it becomes negatively charged and forms an anion.
• Electron loss: When an atom or molecule loses one or more electrons, it becomes positively charged and forms a cation.

Types of Ions

There are two main types of ions:

• Cations: Positively charged ions formed by the loss of electrons.
• Anions: Negatively charged ions formed by the gain of electrons.

Examples of Ion Formation

Here are some examples of ion formation:

• Sodium (Na) + Chlorine (Cl): When sodium loses an electron, it forms a positively charged sodium ion (Na+). When chlorine gains an electron, it forms a negatively charged chloride ion (Cl-).
• Calcium (Ca) + Oxygen (O): When calcium loses two electrons, it forms a positively charged calcium ion (Ca2+). When oxygen gains two electrons, it forms a negatively charged oxide ion (O2-).
