QUESTION

# Can't we use hybridization concept for ionic compounds?with the help of hybridization we can predict shape of compound ,so if it is not applicable in ionic compounds how can we predict shape of ionic compounds?

The was put together to try and explain , the in which electrons are shared by the two atoms.

This is not the case for , for which the difference in between the two atoms (or molecules) is large enough that electrons are no longer shared, but transferred - lost and gained.

This gives rise to a postively-charged and a negatively-charged ion, which are bonded together by the electrostatic force of attraction. No hybridization is needed for these since we know how bond - one atom loses electrons, the other one gains them.

On the other hand, hybrodization successfully explained . A classic example is C's abillity to form 4 bonds, despite the fact that it only has 2 unpaired electrons in its outermost shell.

One electron is promoted from the 2s-orbital to the 2p-orbital, creating four sp^3 hybridized orbitals that hold 1 unpaired electron each, thus explaining how four bonds can be possible.

When it comes to the shape of an , hybridization again cannot be used since these compounds have no definite shape.

The alternating positively-charged and negatively-charged ions which form an ionic compound arrange themselves in a tightly-packed crystal lattice structure.

This crystal lattice structure helps keep the ions tightly together, and is the reason for why ionic compounds are solid at room temperature.
