The following table gives the crystalline structure of the most thermodynamically stable form(s) for elements that are solid at standard temperature and pressure. Each element is shaded by a color representing its respective Bravais lattice, except that all orthorhombic lattices are grouped together.
A heavy, silvery d-block element, mercury is the only metallic element that is known to be liquid at standard temperature and pressure; [a] the only other element that is liquid under these conditions is the halogen bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature.

The periodic table is a graphic description of the periodic law, [36] which states that the properties and atomic structures of the chemical elements are a periodic function of their atomic number. [37]
Discovered by the French chemist Paul-Émile Lecoq de Boisbaudran in 1875, [13] gallium is in group 13 of the periodic table and is similar to the other metals of the group (aluminium, indium, and thallium). Elemental gallium is a relatively soft, silvery metal at standard temperature and pressure. In its liquid state, it becomes silvery white.

In the periodic table, it appears between the lanthanides lanthanum to its left and praseodymium to its right, and above the actinide thorium. It is a ductile metal with a hardness similar to that of silver. [9] Its 58 electrons are arranged in the configuration [Xe]4f 1 5d 1 6s 2, of which the four outer electrons are valence electrons. [10]
Germanium occurs mostly in the oxidation state +4 although many +2 compounds are known. [42] Other oxidation states are rare: +3 is found in compounds such as Ge 2 Cl 6, and +3 and +1 are found on the surface of oxides, [43] or negative oxidation states in germanides, such as −4 in Mg 2 Ge.
