Take the local train, Circumvesuviana, from the Sorrento Central train station to the Naples Central Railway Station. Sorrento is the last and first stop on its trip around the Gulf of Naples, so you don't have to worry about getting on a train in the wrong direction. Train fare costs about $5.50.
How elements are formed. Our world is made of elements and combinations of elements called compounds. An element is a pure substance made of atoms that are all of the same type. At present, 116 elements are known, and only about 90 of these occur naturally.
Elements come together to form compounds. Compounds are things like halite (a.k.a salt, made of sodium and chloride). Elements are simple and can not be simplified. Elements are made out of specific combinations of atoms. Elements are important because they form compounds that make humans, water, food, and other objects. They can be gases, solids, and liquids. Some are stable while others aren't.
