Of the two compounds sif4 and sf4, which is polar and which is nonpolar?

SiF4 has a overall non polar bond because there will only be the same compound in the outer layer, what’s interesting is the internal bonds are polar in nature as the electronegative value difference is more than 0.5. SF4 have the bond polar in nature as the electronegative value difference is almost 3 and the electrons are not shared equally when represented in Lewis structure.

Volume is a measure of the amount of space an object takes up. When a cylinder is submerged in the water it pushes water out of the way. If you measure the amount the water level increases, you can find the volume of the water pushed out of the way.
