Ionic bonding is important in many everyday things. Here are some common examples:

1. Table Salt (NaCl): Sodium (Na) gives away one tiny particle called an electron. When this happens, it becomes a sodium ion (Na$^+$). On the other hand, chlorine (Cl) takes in an electron, becoming a chloride ion (Cl$^-$). The positive sodium ions and negative chloride ions stick together, forming ionic bonds in salt. Every year, about 60 million tons of salt are made for eating and other uses.

2. Baking Soda (NaHCO$_3$): In baking soda, sodium ions team up with bicarbonate ions (HCO$_3^-$). This mix shows some key signs of ionic bonding, like high melting and boiling points. The money made from baking soda around the world is expected to hit $2.5 billion by 2026.

3. Calcium Fluoride (CaF$_2$): Calcium (Ca) gives away two electrons to become a calcium ion (Ca$^{2+}$). Two fluorine atoms each take one electron and become two fluoride ions (F$^-$). This ionic compound is often found in toothpaste and helps provide fluoride, which is good for teeth.

4. Potassium Iodide (KI): Potassium (K) gives an electron to iodine (I) to create potassium iodide. This compound is very important for health and medicine. Each year, about 1,000 tons of potassium iodide are produced.

These examples show how useful ionic bonding is in our daily lives.
