Explanation:
Ions are the charged species that contain one or more valence electrons
Ex–> Na+, O-2
Answer:
Ions are atoms or molecules that have gained or lost electrons, resulting in a net positive or negative charge. They play a crucial role in many chemical reactions and are found in various aspects of our daily lives. Here are a few examples of ions:
1. Sodium ion (Na+): Sodium loses one electron to become positively charged.
2. Chloride ion (Cl-): Chlorine gains one electron to become negatively charged.
3. Calcium ion (Ca2+): Calcium loses two electrons to become positively charged.
4. Nitrate ion (NO3-): Nitrate has a negative charge due to the presence of three oxygen atoms.
5. Hydrogen ion (H+): Hydrogen loses its only electron to become positively charged.
