Metals vs. Nonmetals
By Kelly Moran
From this unit in the book, I've learned a lot about the differences between metals and nonmetals. Metals have luster (are shiny on the outside) while nonmetals are not shiny at all and quite dull in appearance. Metals are malleable (can be bent and flattened by a hammer) and ductile (able to be drawn into strings and are flexible) while nonmetals are brittle (easily cracked and shattered). Nonmetals are usually unable to conduct electricity (with exceptions like the element Carbon) while most metals are all able to conduct electricity. Metals are very chemically reactive to substances like acid and copper (which is a type of metal). Many nonmetals are also chemically reactive. Both metals and nonmetals are similar in that they are both chemically reactive to things. Metals are very durable and are able to withhold the same color and shape for a long period of time but nonmetals are the opposite and die out and change colors quickly. In all, nonmetals and metals are basically opposites but they are similar in that they are both chemically reactive to substances and both are used to conduct things. For example, metal conducts electricity while nonmetals conduct heat.
