VSEPR (Valence Shell Electron Pair Repulsion) theory is a model used to predict the geometry of individual molecules based on the repulsion between electron pairs in the valence shell of the central atom.

Molecules with four bonding pairs of electrons have a tetrahedral shape.

1s2 2s2 2p6 3s2 3p6 4s2.

The products are sodium chloride (NaCl) and water (H2O).

The shape of difluoromethane (CH2F2) is tetrahedral.

The product is silver chloride (AgCl).

Electron configuration describes the distribution of electrons in an atom's orbitals.

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

A covalent bond is a chemical bond formed when two atoms share one or more pairs of electrons.

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.
