Question

Explain the bonding formation of the following
1.oxygen
2.water
3.ammonia

Answer 1

Oxygen

In a covalent bond, electrons are shared between two atoms. When twooxygen atoms bond together to form an oxygen molecule, they share four electrons – two from each oxygen atom.

Water

In the formation of water molecule, oxygen atom completes its octet by sharing one electron each with two hydrogen atoms. Similarly, each hydrogen atom completes its duplet by sharing one electron with oxygen atom. Thus, two separate single co-valent bonds are formed between hydrogen & oxygen atoms.

Ammonia

Ammonia is formed from 3 atoms of Hydrogen and 1 atom of Nitrogen. Nitrogen has 5 Valence Electrons ( 2,5 ) in its outer shell, so the valence electrons of 3 hydrogen atoms gets shared and it forms Ammonia through Co-valent bonding.
