Whenever a non-metallic combines with another non metal, sharing of electron takes place between their atoms and a covalent bond is formed. A covalent bond can also be formed between two atoms of the same non-metal. The shared electrons are counted with both the atoms due to which each atom in the resulting molecule gets an inert gas electron arrangement of 8 electrons (or 2-electrons) in the outermost shell eg : $H_{2}$ molecule.
Draw the electron dot structures for the following molecules.
1. Chlorine 2. Hydrogen chloride
3. Methane 4. Carbon dioxide
5. Ammonia 6. Water
7. Oxygen 8. Ethane
9. Nitrogen 10. Acetylene
