What is the significance of the VSEPR theory in covalent bonding?

Back

VSEPR (Valence Shell Electron Pair Repulsion) theory helps predict the shape of molecules based on the repulsion between electron pairs in the valence shell.

How do you determine the number of valence electrons in an atom?

Back

The number of valence electrons is determined by the group number of the element in the periodic table.

What is the difference between a polar and nonpolar covalent bond?

Back

A polar covalent bond occurs when electrons are shared unequally between atoms, while a nonpolar covalent bond occurs when electrons are shared equally.
