= PERIODIC TABLE =
 * ==Mendeleev developed the first periodic table of the elements based on atomic mass.==
 * ==Today's periodic table is arranged according to atomic number.==
 * ==An element's properties can be predicted from its location in the periodic table.==
 * ==Each square on the periodic table contains information about one element. Information includes its atomic number, chemical symbol, name, and atomic mass.==
 * ==The main body of the periodic table is arranged into 18 columns, called groups, and 7 rows, called periods.==
 * ==The properties of each element can be predicted from its location in periodic table.==

** METALS **
 * **Most of the elements are metals.**
 * **Metals are found to the left of the zigzag line in the periodic table.**
 * **The reactivity of the metals tends to decrease as you move from left to right across the periodic table.**
 * **Metals are shiny, hard, malleable, and excellent conductors.**

NONMETALS
 * **There are 17 nonmetals.**
 * **The nonmetals are located to the right of the zigzag line in the periodic table.**
 * **Nonmetals lack the characteristic properties of metals. Nonmetals are dull, brittle, and poor conductors.**
 * **Nonmetals can react with metals and nonmetals.**

METALLOIDS


 * =The 7 metalloids are located on the border between metals and nonmetals.=
 * =Metalloids have some characteristics of both metals and nonmetals.=
