CHem 1211- Ch 4 Flashcards | Quizlet

When a metal reacts with a nonmetal, an ionic compound is formed. A metal-nonmetal reaction can always be assumed to be an oxidation-reduction reaction. Two nonmetals can undergo an oxidation-reduction reaction. When two nonmetals react, the compound formed is ionic. A metal-nonmetal reaction involves electron transfer.

Interesting and Useful Facts about Iron - ThoughtCo

Iron is an element that has been known in its pure form for at least 5,000 years. The name "iron" comes from the Anglo-Saxon word "iron" and Scandinavian "iarn" for the metal. The element syol for iron is Fe, which comes from the Latin word for iron, "ferrum". Iron is one of the most plentiful elements.

Silver, Chemical Element - reaction, water, uses, …

Chemical properties Silver is a very inactive metal. It does not react with oxygen in the air under normal circumstances. It does react slowly with sulfur compounds in the air, however. The product of this reaction is silver sulfide (Ag 2 S), a black compound. The tarnish that develops over time on silverware and other silver-plated objects is silver sulfide.

One possibility is to discuss lattice energy, using as an example from everyday life cold packs that rely on an endothermic reaction triggered by bending a metal plate. The following activity can then be used to introduce the notion of hydration energy and to demonstrate that the reaction by which some salts dissolve is an exothermic reaction.
