both NH3 and SO2 and NH4+ have hybridization sp3

 

[DrClaude]

both NH3 and SO2 and NH4+ have hybridization sp3

That is incorrect.

i just googled i found out that so2 is sp2, but why?! S has 6 valence elctrons two engage in sigma bond with two oxygens, and remains two pairs of electrons which means 4 hybridized orbitals SP3!

In addition to the two sigma bonds, two pi bonds are formed with the oxygens, and a lone pair is left on the sulfur, so it is hybridized sp2.

Try to draw a Lewis dot structure. There are no two pairs.

yes u are right it's NH3 and NH4+ because both are sp3, thx
