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.
The regions on the periodic table are arranged in the following order from left to right: alkali metals, alkaline earth metals, transition metals, metalloids, nonmetals, halogens, noble gases, and actinides.
Metals,Non-Metals,Metalloids, noble gases and rare metals
metals
Non-metals on the periodic table include hydrogen, carbon, nitrogen, oxygen, fluorine, and chlorine. Metalloids are elements that have properties of both metals and non-metals, such as boron, silicon, germanium, arsenic, antimony, and tellurium. There are 7 metalloids in total on the periodic table.
The 4 divisions are Alkali Metals,Transitional Metals, Halogens,Noble Gases .
The three major groups of elements on the periodic table are metals, nonmetals, and metalloids. Metals are typically shiny, conduct heat and electricity well, while nonmetals are usually dull, poor conductors, and can be gases. Metalloids share properties of both metals and nonmetals.
Metals have the greatest number of elements among the classifications mentioned – they include a large majority of the known elements in the periodic table. Non-metals, metalloids, and rare gases have fewer elements in comparison to metals.
The periodic table consists of different types of elements, including metals (such as iron and copper), non-metals (such as oxygen and sulfur), metalloids (such as silicon and arsenic), noble gases (such as helium and neon), and transitional metals (such as iron and gold).
Non-metals, they are all 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

Radioactive elements are in the groups (columns) to the left. On the right, there is non-radioactive metals, gases, and metalloids.
