How do you classify elements on the periodic table?
Elements of the periodic table are grouped as metals, metalloids or semimetals, and nonmetals. The metalloids separate the metals and nonmetals on a periodic table. Also, many periodic tables have a stair-step line on the table identifying the element groups. The line begins at boron (B) and extends down to polonium (Po).

Which part of the periodic table is metal?
In other words, metals have a tendency to lose electrons. So the elements having metallic nature are found on the left and middle part of the Periodic table as shown in the above image.
What are elements that have metallic properties as well as nonmetallic properties called?
They are found between the metals and nonmetals. Elements which have the metallic properties as well as nonmetallic properties are classified as Metalloids. Because of this reason, they are also known as semimetals.
Which element is in the top right corner of the periodic table?
Elements which are in the top right corner of the Periodic table are classified as Nonmetals (Hydrogen is also a nonmetal which is located in the group 1). Nonmetals have the tendency to gain the electrons during a chemical reaction. In other words, the elements which gain electrons during a chemical reaction are classified as Nonmetals.
