Question

Using electron-dot diagrams which show only the outermost shell electrons, show how a molecule of oxygen, O2, is formed from two oxygen atoms. What name is given to this type of bonding? (At. No. of oxygen = 8)

Answer 2

Explanation:

• The atomic number of oxygen s 6. The electronic configuration of the oxygen atoms depicts that the outermost shell of the element contains 6 electrons.
• So in order to achieve the 8-electron structure of an inert gas i.e., to achieve octate or to attain noble gas configuration, the element needs more 2 electrons.
• Hence, another Oxygen atom combines with the already present oxygen atom to form a molecule of oxygen gas.
• This type of bonding is called as double covalent bonding.
