Why does sulfate have 4 Oxygens?
Sulfate is a polyatomic ion with 1 sulfur (6 valence electrons), 4 oxygens (4 x 6 valence electrons = 24 e-) and a charge of -2 (2 valence electrons). If we add all the electrons together we get 32 valence electrons with which to make bonds and lone pairs around the atoms in the ion.
Why the Valency of SO4 is 2?
b• Sulphur has 6 electrons in its Valence shell& oxygen has a oxidation no. -2 so when 4 oxygens combine with 1 Sulphur , the octet of the Sulphur is extended by by 2 more electrons(Sulphur has 6 electrons & 4Oxygens gives it 8 electrons i.e., 2 more electrons) which gives SO4 a oxidation no. Of -2 & valency 2.

Is BeCl2 a resonance?
Beryllium chloride has a significant ionic contribution to its electronic structure. A quick calculation, DF-BP86/def2-SVP, reveals that the charge of beryllium is q(Be)=0.8 and of chlorine q(Cl)=−0.4, based on natural bond orbital analysis. For these bonding situation, resonance is unavoidable.

What is the shape of ASF 5?
trigonal bipyramidal
What is the shape of BeCl2 using Vsepr model?
linear
What is the shape of CH4?
tetrahedral
Is ch4 a Vsepr shape?
The coordination geometry of carbon is consequently tetrahedral. There are four bonded groups, therefore there are no lone pairs….VSEPR calculation for methane, CH. 4.
