Covalent Bond (2)

Chemistry

Not quite remember

I easily remember

Formation of covalent bonds

Covalent bonds are formed when non-metal atoms share their electrons to achieve a stable duplet or octet electron arrangement

Types of covalent bonds

There are three types of covalent bonds; single bond, double bond and triple bond

The property of diamond that is one of the hardest substances in the world

The property of diamond is caused by the formation of covalent bonds between carbon atoms

Formation of covalent bond (single bond)

A single bond is formed when two atoms share a pair of electrons

Lewis structure (1)

The formation of covalent bond can be visualised using the Lewis structure

Lewis structure (2)

Lewis structure only shows the valence electrons of the atoms involved

Lewis structure (3)

A pair of electrons shared, is represented with a line between the two atoms

Formation of covalent bond (double bond)

A double bond is formed when two atoms share two pairs of electrons

Formation of covalent bond (triple bond)

A triple bond is formed when two atoms share three pairs of electrons

Example of formation of single bond in chlorine molecule, Cl2 (1)

Chlorine atom, Cl needs one electron to achieve a stable octet electron arrangement
