2 Many molecular model systems use perforated Styrofoam wood

2. Many molecular model systems use perforated Styrofoam, wooden, or plastic balls to represent atoms and wooden sticks to connect the atom models. The ball and stick model gives the impression of a rigid chemical bond. a. Based on your observation on the \"Phet atomic interactions\" simulation, rather than describing a chemical bond as rigid as a wooden stick, how would you describe the interaction of two atoms in a covalent bond? b. Based on the behavior of the interacting atoms, how would you define \"bond length\"? How would you define \"bond dissociation energy\"? c.

Solution

a) covalent bond is formed by shared pair of electrons between two atoms. In a covalent bond intermolecular forces takes place rather than intramolecular forces.Intermolecular forces are much more stronger..

b) bond length is defined as the average distance between the centres of two covalently bonded atoms. If the bond length is less it means stronger is the intermolecular interactions and larger will be bond energy.

C) bond dissociation energy is the energy required to break one mole of covalently bonded atoms.
