When we study the elements, it is important to know which elements are metals and which ones are not. The vertical columns of elements are called groups, or families. ­The columns that comprise the periodic table are called groups-- 18 in total.Groups indicate elements with similar chemical and physical properties. Also, many periodic tables have a stair-step line on the table identifying the element groups.

As opposed to metals, non-metallic elements are very brittle, and cannot be rolled into wires or pounded into sheets. The position of an element provides information about its properties. How metalloids behave in chemical interactions with other elements depends mainly on the number of electrons in the outer energy level of their atoms. information and properties of metals in periodic table. Home; Periodic Chart; PDF; Timeline; Dictionary; Quiz; Games; Resources; Electron Configuration; Differences of metals and nonmetals. Elements of the periodic table are grouped as metals, metalloids or semimetals, and nonmetals. These elements are distinctive in that they typically have low melting and boiling points, don't conduct heat or electricity very well, and tend to have high ionization energies and electronegativity values. Many nonmetals can gain metallic properties under very high pressures. The line begins at boron (B) and extends down to polonium (Po). The metalloids separate the metals and nonmetals on a periodic table. Water is made up of the two nonmetals oxygen and hydrogen. The Periodic Table contains a lot of useful information on the elements. Non-metals are not able to conduct electricity or heat very well. Only eighteen elements in the periodic table are generally considered asnonmetals. In the periodic table of elements, there are seven horizontal rows of elements called periods. The most common way the periodic table is classified by metals, nonmetals, and metalloids. They fall between metals and nonmetals in the periodic table. Metalloids may act either like metals or nonmetals in chemical reactions. Some elements appear in both metallic and non-metallic forms. Periodic Table of Elements.

But nonmetals make up most of the crust, atmosphere and oceans of the earth. The nonmetals list which makes up the periodic table includes hydrogen, helium, carbon, sulfur, nitrogen, oxygen, radon, neon, other halogens, and noble gases etc.. The elements are divided into two main types, metals and nonmetals, based on their properties. This is a list of the nonmetals in order of increasing atomic number. About 80 percent of the elements are metals (shiny elements that conduct heat and electricity well), and 15 percent of the elements are nonmetals (poor conductors of heat and electricity). About 91 of the 118 elements in the periodic table are metals; the others are nonmetals or metalloids. The nonmetals are located on the upper right side of the periodic table.
