Metal, non-metal, and metalloid.
Hydrogen is placed separately. It has one valence electron. It is placed at the top in periodic table.
metals, nonmetals, gases.
The three main categories of elements on the periodic table are metals, metalloids, and nonmetals.
the three main categories are non-metal, metal, and metaloid. those are the main categories of the periodic table.
Three main classes are:MetalsNon metalsTransition elementsThey are present in periodic table.
The three main metals in a periodic table are transition metals, alkali metals, and alakaline earth metals.
the periodic table is divided in three main sections. the section's are the metals, the non metals, and the metalloids.
The periodic table has three main groups: metals, non-metals and metalloids. Metals are solid and conductors of electricity. Metals can be found in the left of the periodic table.
Metals nonmetals and metalliods
There are three main groups of elements on the Periodic Table. They are Metals, Metaloids, and Non-Metals. Metaloids have properties of both metals and non-metals.

The main group elements of the periodic table are groups 1, 2 and 13 through 18
The two bottom rows of periodic table are: Lanthanoids Actinoids They are placed separately from the main periodic table.
Alkali, Alkaline earth, Halogen, oxygen, Nitrogen, carbon are the main families in the periodic table.

It organizes the elements.
Metals, non metals, transition elements belong to main periodic table. They are arranged according to atomic number.
In Mendeleev's periodic table, the elements were arranged in the increasing order of their atomic masses and repeating periodic properties.
