Bond length: length:<br />

The optimum distance between<br />

nuclei involved in a covalent <strong>bond</strong>. If the<br />

atoms are too far apart, the attractive forces<br />

are small and no <strong>bond</strong> exists. If the atoms<br />

are too close, the repulsive interaction<br />

between the nuclei is so strong that it pushes<br />

the atoms apart, Fig 5.2.<br />
