What are the categories of compounds?

1 Answer

There are three basic categories of compounds, based on the type of bonding: ionic, polar covalent, and nonpolar covalent.


The probability of finding the electron closer to one atom or the other in the bond determines the type of compound formed.

In an ionic bond, the probability of finding an electron near one atom is very small while the probability of finding the electron very close to the other atom is quite high.

In a polar covalent bond, the electrons spend most of their time nearer to one atom than the other.

In a nonpolar covalent bond, the electrons are shared almost equally between each atom.
