Light metals Heavy metals Periodic table location: Most found in groups 1 and 2 [145] Nearly all found in groups 3 through 16: Abundance in Earth's crust [108] [146] More abundant: Less abundant Main occurrence (or source) Lithophiles [110] Lithophiles or chalcophiles (Au is a siderophile) Reactivity [57] [146] More reactive: Less reactive Sulfides
The Periodic Table of the Elements in Pictures.pdf. English: This pictorial periodic table is colorful, boring, and packed with information. In addition to the element's name, symbol, and atomic number, each element box has a drawing of one of the element's main human uses or natural occurrences. The table is color-coded to show the chemical ...

Superheavy elements, also known as transactinide elements, transactinides, or super-heavy elements, or superheavies for short, are the chemical elements with atomic number greater than 104. [ 1 ] The superheavy elements are those beyond the actinides in the periodic table; the last actinide is lawrencium (atomic number 103).
In astronomy metal refers to all chemical elements in a star that are heavier than helium. In this sense the first four "metals" collecting in stellar cores through nucleosynthesis are carbon, nitrogen, oxygen, and neon. A star fuses lighter atoms, mostly hydrogen and helium, into heavier atoms over its lifetime.
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. [ b ]
e. The chemical elements can be broadly divided into metals, metalloids, and nonmetals according to their shared physical and chemical properties. All elemental metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metallic elements; and have at least one basic oxide.
Contents. Periodic table (crystal structure) For elements that are solid at standard temperature and pressure the first table gives the crystalline structure of the most thermodynamically stable form (s) in those conditions. Each element is shaded by a color representing its respective Bravais lattice, except that all orthorhombic lattices are ...
