The periodic table is a graphical representation of the chemical elements, arranged according to their atomic number, electron configurations, and chemical properties. The elements are grouped into different categories based on their properties, and one of the main categories is the metals.Metals are located on the left side and in the center of the periodic table. They are characterized by their shiny appearance, high thermal and electrical conductivity, and the ability to lose electrons and form positive ions. Most of the elements in the periodic table are metals, with the exception of hydrogen, helium, carbon, nitrogen, oxygen, and the halogens.The metals can be further divided into different categories based on their properties and behavior. The alkali metals, located in Group 1, are the most reactive metals and include lithium, sodium, and potassium. The alkaline earth metals, located in Group 2, are less reactive than the alkali metals and include beryllium, magnesium, and calcium. The transition metals, located in the middle of the periodic table, have intermediate reactivity and include copper, iron, and gold. The post-transition metals, located in Group 13 to 18, are less reactive than the transition metals and include aluminum, zinc, and lead.The metallic character of an element decreases as we move from left to right across the periodic table, and from top to bottom within a group. The elements on the left side of the table are the most metallic, and those on the right side are the least metallic. Elements in the center of the table, such as copper and silver, are considered 'typical' metals, while those on the left side, such as lithium and sodium, are highly reactive and are not found in nature as pure elements.In addition to the elements, there are also metalloids, which are elements that have properties of both metals and non-metals, are located on the stair-step line of the periodic table, from boron to polonium.In conclusion, metals are located on the left side and in the center of the periodic table. They are characterized by their shiny appearance, high thermal and electrical conductivity, and the ability to lose electrons and form positive ions.
