- Our lessonnext week will be about ionic compounds. I want to advance! I know little about ionic compounds!!!
- Hello, Mom!
- Okie, I'll teach you what I know.
- Wow!!!(Salt? Bleach? Toothpaste?)
- Ionic compounds. Hmm…they are compounds formed by transferring electrons from an atom to another.
- Theycan be found here on our home, like the table salt (sodium chloride), bleach(sodium hypochlorite), and in your toothpaste (sodium fluoride).
- Whoa! What are those in real life?
- Umm…Since it’s called ionic compound, how are ions formed?
- First, let’s start with ions. So, what are ions?
- Anion
- Ions are atoms with charge - anion for negative, and cation for positive!
- Cation
- As I said earlier, ions are formed by the addition or removal of electrons on neutral atoms or molecules. For example, let’s say the atoms are sodium and chlorine. Now the sodium gives an electron to chlorine. This creates a sodium cation and chlorine anion.
- And the chlorine becomes chloride. It’s now sodium chloride – an ionic compound!
- That’s right!
- Last question… Why are they important?
- Like saltfor adding flavor to meals, bleach for cleaning, and toothpaste for our teeth?
- Ithink it’s because they form ionic compounds which are very useful to us!
