Answer:
Ionic Bonds
An ionic bond is a type of chemical bond that has formed as a result of the complete transfer of valence electrons from one molecule to another. Metals will transfer their valence electrons to non-metals forming a positively-charged ions. The atoms that accept the electrons become negatively-charged. The two opposite charges will be attracted towards each other and form an ionic bond. Many compounds in the world are formed by ionic bonds and are therefore ionic compounds. Different types of salts are ionic compounds.
Examples of Ionic Bonds:
1. Sodium chloride - NaCl - table salt
2. Calcium chloride - CaCl2 – rock salt
3. Sodium hydroxide - NaOH - Lye used in soap
4. Sodium fluoride - NaF – fluoride in toothpaste
5. Iron Oxide – Fe2O3 - rust
6. Calcium hydroxide – Ca(OH)2 – basic salt in antacid tablets
