Classes+of+Elements

Irina and Cinthia Elements are analyzed as solids, liquids, or gases. The symbols for solids, liquids, and gases are different. The symbols for solids are black, symbols for liquids are purple, and the symbols for gases are red. There are many ways of telling the difference between elements. One way of telling the difference Is by the atomic numbers. The symbols for the atomic numbers are in white. Elements with an atomic number of ninety three don’t occur naturally. Then the ones with the atomic number of one through ninety two actually do occur on earth. Many elements are metals so they are classified as metals, nonmetals and metalloids.
 * Classes of Element-**



Metals-

· Chemical properties of nonmetals are elements with usually four to eight electrons in their outer shell. They easily share their electrons with other elements. Nonmetals also gain electrons not like metals that tend to lose the electrons. · Physical properties of nonmetals are their dull appearance. Nonmetals have poor conductors to heat and electricity. Also nonmetals are easily breakable, have a low breaking point and have a low density.
 * Nonmetals-** Elements are also notified as nonmetals. Nonmetals can be classified by their physical properties and chemical properties.



**Metalloids-** All elements are classified as metals and nonmetals but there are a few that are known as metalloids because of the in-between properties.
