Question
Using electron-dot diagrams which show only the outermost shell electrons, show how a molecule of oxygen, $O_2$, is formed from two oxygen atoms. What name is given to this type of bonding? (At. No. of oxygen = $8$)
✓
Answer
Since an oxygen atom has 6 electrons in its outermost shell so, it needs $2$ more electrons to achieve the stable 8-electron inert gas configuration. Hence, it combines with another oxygen atom and forms a molecule of oxygen.
This type of bonding is called a double covalent bond.
