Definition of the Gallium Element
A rare metallic element that is liquid near room temperature, expands on solidifying, and is found as a trace element in coal, bauxite, and other minerals. Gallium is solid at normal room temperatures is soft enough to be cut with a knife. Along with
Mercury, cesium, and rubidium it becomes liquid when heated slightly.

It is used in semiconductor technology and as a component of various low-melting alloys.  It is stable in air and water; but it reacts with and dissolves in acids and alkalis. The Atomic Number of this element is 31 and the Element Symbol is Ga.

 

Origin / Meaning of the name Gallium
The name originates from the Latin word Gallia meaning France also gallus, meaning "rooster"after the French chemist Paul-Emile Lecoq de Boisbaudan known as 'Lecoq'.

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.

Facts about the Discovery and History of the Gallium Element
Gallium was discovered by Paul Emile Lecoq de Boisbaudran in France in 1875.

What is Gallium - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 and now recognises more periods and elements than Dimitri  Mendeleev knew in his day in his day but still all fitting into his concept of  the "Periodic Table" in which Gallium is just one element that can be found.
