Ionic bonds are very important for understanding how salts and minerals act.
These bonds happen when atoms move electrons around. This creates ions, which are charged particles. Some ions become positive, called cations, and some become negative, called anions.
A good example of this is sodium chloride, which is table salt. Here’s what happens: sodium (Na) loses an electron and becomes Na. At the same time, chlorine (Cl) gains that electron and becomes Cl.
High Melting and Boiling Points:
Ionic compounds like salt have very high melting and boiling points. This is because the attraction between the positive and negative ions is strong. For example, table salt melts at around 801°C!
Solubility in Water:
Most ionic salts dissolve well in water. You can see this by stirring salt into a glass of water. The salt breaks apart into ions and mixes with the water.
Electrical Conductivity:
Solid ionic compounds can’t conduct electricity. But if you heat them up until they melt or if you dissolve them in water, they can carry electricity. This is because the ions can move around freely.
Brittleness:
Ionic compounds are usually brittle. If you hit them hard, the layers of ions can shift. When like-charged ions move close to each other, they repel, causing the structure to break.
These properties show just how important ionic bonds are, both in our daily lives and in industries!
