The 3 main parts of the periodic table are metals, metalloids, and non-metals. The periodic table consists of over one hundred elements, and each element is arranged in order of increasing atomic number. Hydrogen is the first element in the periodic table and belongs to the same position as the metals, but chemists don't see hydrogen as metal, though it can also behave like a metal.
The left-hand side of the periodic table is the part that contains the metals. All of these elements have certain properties in common. For instance, they have; high thermal and electrical conductivity, high melting points, and they readily lose electrons.
The metalloids are in the middle of the periodic table; they fall between the metals and the non-metals. As a result, they share some of the properties of metals and non-metals. Lastly, the right side of the periodic table is the part that contains the non-metals.
