Question

Give the diagrammatic view of formation of oxygen molecule.

Answer 1

• Atomic number of oxygen is 8.
• Electronic configuration is 2,6.
• In the formation of oxygen molecule, each oxygen atom contain 6 valence electrons.
• Each oxygen atom needs two more electrons to attain stability.
• So it shares its two electron with neighbouring oxygen atom.
• They form double covalent bond.
• It represented by double short line($=$)

$\underset{..}{\overset{}{:\mathrm{O}:}}+\underset{..}{\overset{}{:\mathrm{O}:}}\to \stackrel{··}{:\mathrm{O}:}\stackrel{..}{:\mathrm{O}:}$ or $\stackrel{..}{:\mathrm{O}::}\stackrel{..}{\mathrm{O}}:$

$\stackrel{}{:\stackrel{..}{\mathrm{O}}=\stackrel{··}{\mathrm{O}:}}$
