Answer 2

$\mathfrak{\pink{Hybridization}}$

Hybridization is a phenomenon of intermixing of atomic orbitals of almost equal energy.. to form Hybridized orbitals!

$\mathfrak{\green{Hybridization \: in\: \mathbf{\red{NH_{3}}}}}$

➡The chemical name of NH3 is Ammonia

➡Ammonia is formed by one nitrogen and 3 hydrogen atoms

➡In NH3, Nitrogen is the central atom..So, hybridization takes place in nitrogen

Let us know the EC of the both atoms

________________

$_{7}N$ - 1s² 2s² 2px¹ 2py¹ 2pz¹

$_{1}H$ - 1s¹

➡ There are three unpaired electrons in Nitrogen atom.. in the three Orbitals (2P x¹ y¹ z¹)

➡ Here, 2s and 2P x¹ y¹ z¹ orbitals undergoes Sp³ hybridization and forms 4 Sp³ hybridized orbitals

➡ Among 4, One orbital is completely filled. So, only 3 orbitals participates in bonding

➡ There is only one unpaired electron in Hydrogen

➡ Hence, three Hydrogens are required for bonding with Nitrogen

➡ The three Hydrogens, make bond with the nitrogen.. and the bonds formed are, three

$\sigma$Sp³-s bonds

➡ Due, to the lone pair-bond pair repulsion bond angle decreases to

107°31'

➡ Ammonia molecule has the Triagonal pyramidal shape
