How many lone pairs of electrons are there in valence shell of the central atom of SiCl4?

Answer 1

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
