please any body explain hybridizationin NH₃ and H₂O?

H2O, the central oxygen is bonded to the two hydrogens. Overall, there are 8 electrons to draw. Hydrogens need no more than the bond they share with the oxygen, and this is true for any atom they are bonded to. The remaining electrons (4) are placed around the oxygen. So, we add how many atoms are attached to the central, 2 (Hydrogens) and then add how many PAIRS of electrons around the central atom (2) which means SN=4. This has to be the sum of the superscripts. So it has SP3

the hybridizations in both H2O and NH3 are sp3

in H2O the central atom, O, is bonded to 2 H-atoms and has 2 lone pairs. hence the hybridization has to be sp3.

Similarly in NH3, the central atom N is bonded to 3 H-atoms and has 1 lone pair. so its sp3

In NH3 nitrogen is sp3 hybridised. In which 3 orbitals are bonded with hydrohen and forth is lone pair.
The angle between bonds is 107 degree

In H2O oxygen is also sp3 hybridised. In which 2 orbitals are bonded with hydrohen and other two are lone pairs.
The angle between bonds is 105 degree
