However, not all substances or chemical compounds consist of discrete molecules, and indeed most of the solid substances that make up the solid crust, mantle, and core of the Earth are chemical compounds without molecules. These other types of substances, such as ionic compounds and network solids , are organized in such a way as to lack the existence of identifiable molecules per se . Instead, these substances are discussed in terms of formula units or unit cells as the smallest repeating structure within the substance. Examples of such substances are mineral salts (such as table salt ), solids like carbon and diamond, metals, and familiar silica and silicate minerals such as quartz and granite.

Anyone who takes an interest in chemistry, from junior high to collegiate level, can unwind with our chemistry jokes. Some of the jokes’ graphics may help relay visual information that is essential to the learning process. Making connections between difficult chemistry concepts and humor can aid in memorization and comprehension. Humor boosts the brain’s dopamine production, which enhances retention—both long-term memory storage and goal-oriented motivation. For Chemistry Professionals Take a break from the lab and enjoy our chemistry humor. Working on chemistry can be tough. We can help you relax a little.

The Second Law : The biggest, most powerful, most general idea in all of science. A lively, non-mathematical exposition of the way that entropy and activation energy battle it out in the world as we know it. By Frank Lambert of Occidental College. An alternative version , directed to non-science students and adults, is also available. See also Lambert's non-technical description of how activation energies modify the application of the Second Law.
