Answer 2

Metals are the elements which exhibit the highest degree of metallic behaviour is known as metals, on the contrary Nonmetals are such elements which do not possess any metallic behaviour, and Metalloids are those elements, that possess some of the properties like metal, while some like nonmetal.

Metals are placed on the left side of the periodic table, and Nonmetals are placed on the right side of the periodic table and metalloids are placed in the middle of the periodic table.

Metals are located in s, p, d, and f blocks in the periodic table, though nonmetals are located in s and p blocks and metalloids are located in p block of the periodic table.

Metals have a shiny appearance, and nonmetals have a dull appearance; however, metalloids have a shiny and dull appearance.

Thermal and electrical conductivity is high in metals, low in nonmetals, and it is good though is less than metals in metalloids.

Metals have low electronegativity as compare to nonmetals, but metalloids are at an intermediate stage that possesses neither the too high or too low value of electronegativity.

Metals show ductility and malleability, but nonmetals and metalloids do not display this kind of property.
