13 May Ionic Bonding
Ionic Bonding is a type of chemical bond that extracts two oppositely charged ions. It is the transfer of valence electrons that comprehend between atoms. The terms cations and anions are the net electrical charge of ions. In ionic bonding, a metal loses electrons to transfer into a positively charged cation, the non-metals, on the other hand, accepts those electrons to convert to negatively charged anion. In simple words, chemical bonds are generated when the total energy between bonded atoms is lower than the total energy of separate atoms. There is an electron donor (metal) and an electron acceptor (non-metal) required to form ionic bonds. Salts of different types are ionic compounds. Certain examples of Ionic Bonds include:
- Table salt: NaCl (Sodium Chloride)
- Rock Salt: CaCl2(Calcium Chloride)
- Basic Salt: Ca (OH)2(Calcium Hydroxide)
- Fluoride in toothpaste: NaF (Sodium Fluoride)
Another significant term in this subject is covalent bonding. Also known as a molecular bond, it is a chemical bond that includes the sharing of electron pairs between atoms. The stable balance of attractive and repulsive forces amongst atoms when they share electrons is known as covalent bonding. The electron pairs are also known as shared pairs or bonding pairs. Covalent bonding occurs primarily between non-metals elements and in compounds formed between non- metals.
In a structural depiction of molecules, covalent bonds are shown by solid lines joining pairs of atoms, for example:
A single line (-) indicates a bond between two atoms (involving one electron pair), a double line implies a bond between two electron pairs and a triple line represent a triple bond, for example: Carbon monoxide (C O).
Starting from middle school, students are taught of ionic and covalent bonding. Chemistry tuitions are attained by providing animations and drawings that make the concept much simpler. Educators make it a fun learning subject by giving various illustrations.
