metalloids are the seven elements on the "staircase"(bold line located in the middle of the table) they are B, Si, Ge, As, Sb, Te, At.
all metals are found on the left side of the "staircase"
all non metals are found on the right side of the "staircase"
exception to the rule: hydrogen, it is a non metal
A quick way to place an element in a group is to look at a Periodic Table of the elements, particularly one that is color coded to help you quickly identify the groups of elements. We commonly see the elements divided into eight different groups to "capture" elements that have chemical similarities. On a standard periodic table, the metals are on the left. The first two columns are the alkali metals and alkaline earth metals, respectively. The transition metals stretch way on across through the so-called poor metals to the metaloids on the right. We next see the nonmetals, then the halogens, which are all in the next-to-the-last column. In the last column are posted the inert gases or noble gases. Use the link below to take you to the Wikipedia post showing a standard periodic table. Pay attention to the colors of the tiles of each element as you scan the table from left to right. They change toward the right hand side, and those elements that are nonmetals and inert gases are clustered on that right side.
Metals are found in the green background and nonmetals are found in the purple, orange, and blue backgrounds and the very left that is hydrogen in the periodic table.
metals non metals and noble gases in the periodic table of elements?
Metals - Group-1,2
Non-metals- Group-15,16,17
Noble gases- Group-18
Noble gases are non metals
The 4 divisions are Alkali Metals,Transitional Metals, Halogens,Noble Gases .
There are no metals in noble gases.All are gases in noble gases.
- The Group 1A elements are called alkali metals. - The Group 2A elements are called alkaline earth metals. - The nonmetals of Group 7A are called halogens. - The Group 8A elements are called the Noble Gases
Most reactive metals are alkali metals, most reactive nonmetalas are halogens.Least reactive metals are platinum metals; least reactive nonmetals are noble gases.
metals
Noble gases are non metals
yes all noble gases are non metals in the sense that they are not metals ,but they are in no way similar to nonmetals that they should be grouped together , they are after all the noble in nature . :)

All the members of the noble gases family (group 18 of the periodic table) are gases at room temperature.
1. metals
Most elements are metals.
The right side of the periodic table consists of non metals. It contains non metals such as carbon, and gases such as the noble gases.
The regions or sections of the periodic table of elements are, the metals, the transition state elements, the nonmetals, the noble gases, and underneath those regions, the lanthanide series and the actinide series. Hydrogen is sometimes placed above all the other sections, by itself. Technically it is a metal (even though it does not look like one under normal conditions). It has a single valence electron.
