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 are made up of atoms, the smallest particle that has any of the properties of the element.John Dalton, in 1803, proposed a modern theory of the atom based on the following assumptions. 1. Matter is made up of atoms that are indivisible and indestructible. 2. All atoms of an element are identical.
