the Periodic Table is arranged by properties (or more accurately, electronic configuration).
chemicals on the left have similar properties to others on the left and the ones on the right have similar properties to those on the right. you could draw the periodic table backwards and still be technicly correct, although there are reasons this is not done.
one such reason is simple numerics, the atoms of each element count up in atomic weight from left to right (as is the norm in the English language) whereas the lower rows each corespond to the number of electron shells.
for example lithium is above sodium and therefore sodium has one more electron shell but the same number of "free" electrons.
Noble gases have 8 valence electrons. The periodic table of elements starts at the left with the elements that have 1 valence electron, the next column contains the elements that have 2 valence electrons, and so forth (with an interruption for the transition state elements) until you get to 8. After 8, you move to the next row and start at 1 again. That's why the noble gases are on the right side.
Left side and lower part
Metals are located to the left of the stair-step line on the periodic table.
Metals are located in the left hand side of the periodic table, non metals are located on the right and metalloids are located in between as a 'bridge'.
On some periodic tables metals have a different color.
Nonmetals are located in the right corner of the periodic table of Mendeleev. See the link bellow for a periodic table. What? The nonmetals are located on the right of the periodic table, such as oxygen, nitrogen and chlorine.
metals are on the right side and non-metals are on the left side.

There is a stair in the Periodic Table running along groups 13 to 17. The elements on the stairs are metalloids whereas the elements to its right are non-metals. Metals lie on the left side of the stairs.
Metals especially the alkali metals and alkaline earths.
Metals are located to the left of the stair-step line on the periodic table.
Metals are located in the left hand side of the periodic table, non metals are located on the right and metalloids are located in between as a 'bridge'.
The non-metals are located on the right side of the table. The metals are located on the left hand side. The metaloids are located in the middle towards the right. As a general rule going down the table increases the metallic tendency and going across the table from left to right reduces the metallic character.
On some periodic tables metals have a different color.
Non-metals are located on the very right of the Periodic Table. Metals are on the left.
Metals are found on the left hand side on the Periodic Table (towards the left of the "staircase". The "staircase" line divides elements into metals and non-metals. Elements to the right of the "staircase" are the non-metals. However, those close to the staircase have both metallic and non-metallic properties and hence are called metalliods.
The metalloids split the table these are a diagonal group of elements, B, Si, Ge, As, Sb and Te. To their right are the non metals to the left the metals. There are many more metals than any other type of element. See Wikipedia article "Periodic table (metals and non metals)"
