5.1 What is a Chemical Bond When two atoms of same or different elements approach each other, the energy of the combination of the atoms becomes less than the sum of the energies of the two separate atoms at a large distance. We say that the two atoms have combined or a bond is formed between the two. The bond is called a chemical bond. Examples and characteristics of 5 types of bonds Increase in bonding energy over similar molecules without hydrogen bonds Hydrogen H 2 O, HF 0.25-0.6 Ne, Ar,Kr, Xe, 0.05-0.2 Low melting and boiling points CHCl 3 Fluctuating or permanent dipole Nondirected bond, structures of very high coordination and density; high electrical conductivity.

Description:
This course is intendedprimarily as an introduction course to materials and solid state chemistry forgraduate students and advanced undergraduate students. The objective is tounderstand solids from a chemical perspective and introduce general solid statesynthesis methodologies and characterization techniques. Topics covered willinclude: structure and structure determination of crystalline solids; freeelectron model for metals; electronic band structure; chemical bonding insolids; structure-property relationships.

'I found the critical re-inspection of familiar concepts such as ionic radii and close packing of spheres most interesting. The author does away with Pauling's rules and the classification of bond types as introduced by Van Arkel and Ketelaar.'--Wolfgang Sachtler, Northwestern University<br>
