How many lone pairs of electrons are on the S atom in sulphur tetra floride (SF4) ?

In case of SF4 there are 6 electrons in the outermost shell of Sulphur, out of these 6 electrons, 4 are utilized in bonding with fluorine and thus two unshared electrons are there. Which leads to the lone pair as shown below. Contribute to make this site more informative.

Why H3PO3 is a diprotic acid? Give reason with structure .

Meaning of diprotic acid is that , it can loose two hydronium ions (H+) . For finding how many H+ ions it can give , we have to see its structure. Here it have only two hydroxyl groups that is -OH groups, and the hydrogen atoms joined to these only are ionisable. So only these

Graphite and Diamond

If diamond and graphite are made of carbon, then why do they look different, and why is diamond harder than graphite? Diamond and graphite are two allotropic forms of Carbon. But still these are very different from one another. 1 Diamond :- In this case each carbon is surrounded by other four carbon atoms in

Why does a covalent bond not form a crystal lattice?

Covalent bond and ionic bond has a very basic difference that is presence of ions or not. The ionic bonds are not limited to one ion only, actually they keep on joining again and again because they are held together by basically the electrostatic forces, due to the oppositely charged ions. lets take example of
