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)
Solution
The atomic number of oxygen is 8. Its electronic configuration is 2, 6. Hence it has six electrons in its outermost shell.
In an oxygen molecule, one oxygen atom shares its two electrons with another oxygen atom. Hence this type of bonding is called covalent bonding.
