Explanation: 

Detailed explanation-1: -Metals: These elements form cation by the loss of an electron. Therefore, metals are called electro-positive elements. Non-metals: These elements generally gain electrons and form anions. Metalloids: The elements that act like both metals and non-metals are called metalloids.

Detailed explanation-2: -The elements can also be divided into two main groups, the metals and the non-metals. Metals are typically have a metallic sheen (shiny) are malleable (bendable) and conduct electricity. Nonmetals typically do not show these properties.

Detailed explanation-3: -The metalloids are a unique group of elements that share properties of both metals and nonmetals. They’re also called the semimetals because of the shared properties of these elements along the dividing line between metals and nonmetals.

Detailed explanation-4: -Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals.

Detailed explanation-5: -Most elements on the periodic table are metals. Examples of metal elements include iron, copper, silver, mercury, lead, aluminum, gold, platinum, zinc, nickel and tin.
