Periodic Table Group and Classification of the of the Gallium Element
Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Gallium classified in the 'Other Metals' section which can be located in groups 13, 14, and 15 of the Periodic Table. All of these elements are solid, have a relatively high density and are opaque. Nearly 75% of all the elements in the Periodic Table are classified as metals which are detailed in the List of Metals.
