Chemical bonds

Ionic bond


Ionic bonding occurs by the passing of electrons between atoms giving rise to stable cations and anions. Notice what happens to the electrons as the atoms approach each other.

Forces in an ionic bond


Two forces are involved in ionic bonding, one attractive and one repulsive. Notice how these forces change depending on the distance between the ions.

Covalent bond


Covalent bonding occurs by the sharing of electron pairs between two atoms. Notice what happens to the electrons when the atoms are brought closer together.

Molecule polarity


When is a molecule polar? Change the electronegativity of the atoms in a molecule to see how it affects polarity. See how the molecule behaves in an electric field. Change the bond angle to see how it affects the polarity shape.
