Explain the three features of chemical bonding.

Question

Quizplus · Accepted Answer

The Answer is All models of chemical bonding have three features in common:

\bullet

Atoms interact with one another to form aggregates such as molecules, compounds, and crystals because doing so lowers the total energy of the system; that is, the aggregates are more stable than the isolated atoms.

\bullet

Energy is required to dissociate bonded atoms or ions into isolated atoms or ions. For ionic solids, in which the ions form a three-dimensional array called a lattice, this energy is called the lattice energy (U), the enthalpy change that occurs when a solid ionic compound is transformed into gaseous ions. For covalent compounds, this energy is called the bond energy, which is the enthalpy change that occurs when a given bond in a gaseous molecule is broken.

\bullet

Each chemical bond is characterized by a particular optimal internuclear distance called the bond distance (r₀).
