Answer:
Metals: Metals are elements having the highest degree of metallic behavior. Metals are found in the left side of the periodic table. They have a characteristic metallic appearance known as luster or shine. Ductility and malleability is a main feature of metals. Malleability refers to a metal’s ability to deform under pressure and ductility refers to its ability to be drawn into wire-like structures.
Metalloids: Metalloids are elements having a low degree of metallic behavior. Metalloids show some metallic properties and some nonmetal properties. The appearance of metalloids can be either dull or shiny. Although they are not excellent thermal and electrical conductors, metalloids are capable of conducting heat and electricity.
Non-Metals: Nonmetals are elements showing less or no metallic properties. Nonmetals have very distinct properties than those of metals and metalloids. Typically nonmetals have a dull appearance since they do not have a metallic appearance.
Noble Gas: The noble gases (historically also the inert gases; sometimes referred to as aerogenes[1]) make up a class of chemical elements with similar properties; under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity.
