The Si has no lone pairs, but each F has 6 lone pairs. Thus 6 x 4 = 24 lone pairs, total.
Ok Um, I do know the Answer, There are no Lone Pairs of Electrons in the Valence Shell of The Central Atom of SiCl4, because: Si has the Number Configuration of: 2,8,4 The '4' is the number of dots, it has surrounding Si, one above Si, one under Si, one on the right side of Si, one on the left side of Si. Cl has the Number Configuration of: 2,8,7 The '7' is the number of dots, it has surrounding Cl, you can have it in any order, i.e. one above Cl, two under Cl, two on the right side of Cl, two on the left side of Cl. But when you join SiCl4 together, and make it into a Lewis Structure, then the Central Atom is Si, Then Si will have one Cl bonding above Si, one Cl bonding under Si, one Cl bonding on the right side of Si, one Cl bonding on the left side of Si, and now all you can see, is that Si has Four Cl, attaching, bonding to Si, and now Si doesnt have any Lone Pairs
In silicon tetrachloride (SiCl₄), there are four bond pairs. Each silicon atom forms a covalent bond with a chlorine atom, resulting in the formation of four Si-Cl bonds, which are considered bond pairs. Thus, SiCl₄ has a total of four bond pairs.
Silicon (Si) has 0 unpaired electrons. It has a total of 4 valence electrons, which it shares to form covalent bonds with other atoms.

Si will have two bonds to the two Hydrogens, and a double bond to the Oxygen. The Oxygen will have two pairs of unpaired valence electrons.

SeI4 is polar.When a compound hasno lone pairs2 lone pairs and 4 atoms4 lone pairs and 2 atoms3 lone pairs and 2 atomsit is non-polar. All others are polar.

The hybridization of Si in SiO2 is sp3.Si : [Ne]3s23p2SiO2 forms a covalent network in which the Si atoms form 4 single bonds to oxygen atoms. The oxygen atoms form 2 single bonds (and have two lone pairs) to Si atoms.Si is in the same group as C but because it contains the d orbitals (empty but there), Si is two large to form pi bonds.
Cl -- S -- Cl ....... .......O Cl -- S -- Cl ....... .......O for some reason wiki is erasing the white spaces needed to format the bonds. ignore the periods as they are space holders. there is a double bond between the O and the S.
The Cl-Si-Cl bond angle in SiCl2F2 is approximately 109.5 degrees, which corresponds to a tetrahedral molecular geometry around the silicon atom. This angle is due to the repulsion between the bonding pairs and lone pairs of electrons around the silicon atom.
Silicon has 4 valence electrons Fluorine has 7 electons each. SiF4 has 4 single bonds. Silicon contributes one electron to each bond and fluorine contributes one electron. Each fluorine has three lone pairs of electrons left over. If I could paste a picture I would but this is the best I could do for a illustration .. : F : .. .. .. : F : Si : F : .. .. .. : F : .. its shape is tetrahedral with 109.5 degrees apart
The Lewis dot diagram for silicon tetrafluoride (SiF4) would show silicon (Si) in the center with four fluorine (F) atoms attached to it, each with one lone pair of electrons. The silicon atom would have no lone pairs of electrons around it.
generally silicon forms covalent bonds. These are generally single bonds- (there are some silenes with Si-Si double bonds but these are unstable compounds.) Si -Si bonds in silanes are known but and while long chain molecules with Si-Si backbones are knwn they are not as stable as the analogous carbon chains. Silicon forms polyatomic anions- so-called silicides- an example is sodium silicide NaSi (Na4Si4) (It contains the Si44- ion which is tetrahedral and isoelectronic with the P4 molecule. This is not the only strange anion- there are others.
