Ionic Bond (3)

Chemistry

Not quite remember

I easily remember

Formation of Ionic Bond

An ionic compound is formed when ions of opposite charges attract one another to form an ionic bond

Example of formation of sodium fluoride, NaF (1)

Sodium atom, Na will donate one electron to achieve a stable octet electron arrangement

Example of formation of sodium fluoride, NaF (2)

Sodium ion, Na+ is formed

Example of formation of sodium fluoride, NaF (3)

Fluoride ion, F– is formed

Example of formation of sodium fluoride, NaF (4)

Sodium ion, Na+ and fluoride ion, F– of opposite charges will attract one another by strong electrostatic attraction force

Example of formation of sodium fluoride, NaF (5)

Electrostatic attraction forces are known as ionic bonds

Example of formation of sodium fluoride, NaF (6)

A compound sodium fluoride, NaF is formed

Characteristics of covalent bonds (1)

The covalent compound consists of simple molecules

Characteristics of covalent bonds (2)

The intermolecular force is weak

Compounds added to toothpaste to strengthen teeth

Calcium carbonate, CaCO3 and sodium fluoride, NaF is also added to toothpaste to strengthen the teeth
