Question

Give the diagrammatic view of the formation of oxygen molecule.

Answer 1

• Electronic configuration of oxygen is 2,6.
• The valence shell of oxygen contain 6 electrons.
• Oxygen needs 2 more electron to attain stable electronic configuration.
• Oxygen shares its 2 electrons with neighbouring oxygen atom.
• By sharing two pairs of electrons, it forms a double bond.
