Actually every element is arranged by atomic number and which electron shell is their outermost one.
most often, the columns in the table share certain characteristics, so the metals, non-metals, and Noble gases (also non-metals) arrange pretty much by column, with columns 1-12 being metals, 13-16 split between metalloids and non-metals, 17 being non-metal only, and 18 being Noble gases.
metals left, nonmetals right and malliods between this two
The metals are on the left and the nonmetals are on the right.
Metals are mostly grouped to the left of the table while the nonmetals are mostly grouped to the right. Metalloids fall in-between.
Metals are present in group-1,2. Non-metals are placed in group-15,16,17. Metalloids are present in a zigzag pattern.
between the metals and the nonmetals along a diagonal line running roughly from boron at the top center roughly to selenium at the right.
1 is least massive leading to the manmade elements in the 100's which are most massive, and also by gasses, non-metals, metaloids and metals'
metals, non metals, metaloids
All the metals are to the left of a thong called a staircase. Along the staircase are all the metaloids. To the right of the staircase are the non metals, halogens and noble gases.
more metals
The 3 main categories are Metal, Nonmetals and Metalloids
Metaloids
Metalloids do not contain either metals or nonmetals. They are elements that have properties of both metals and metalloids, and are found between the metals and nonmetals on the periodic table.
Well, several are, and from left to right. Alkali metals Alkaline earth metals. Transition metals. Metaloids. Nonmetals. Halogens. Nobel gasses.

The three classes of periodic elements are:Metals,that usually tend to lose electrons to form positive ions.Semi-metals or MetalloidsNon-metals,that usually tend to accept electrons to become negative ions.
families determine the energy level of an element and groups determine their properties.
