Chemical properties Light metals Heavy metals Periodic table location: Most found in groups 1 and 2: Nearly all found in groups 3 through 16: Abundance in Earth's crust: More abundant: Less abundant Main occurrence (or source) Lithophiles: Lithophiles or chalcophiles (Au is a siderophile) Reactivity: More reactive: Less reactive Sulfides
Rust is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture. Rust consists of hydrous iron (III) oxides (Fe 2 O 3 ·nH 2 O) and iron (III) oxide-hydroxide (FeO (OH), Fe (OH) 3), and is typically associated with the corrosion of refined iron.

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 ]
Chelation. Chelation is a type of bonding of ions and their molecules to metal ions. It involves the formation or presence of two or more separate coordinate bonds between a polydentate (multiple bonded) ligand and a single central metal atom. [1][2] These ligands are called chelants, chelators, chelating agents, or sequestering agents.
Chemical reaction. A thermite reaction using iron (III) oxide. The sparks flying outwards are globules of molten iron trailing smoke in their wake. A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. [ 1 ] When chemical reactions occur, the atoms are rearranged and the ...
Heavy-metal azides are formed when solutions of sodium azide or HN 3 vapors come into contact with heavy metals (Pb, Hg…) or their salts. Heavy-metal azides can accumulate under certain circumstances, for example, in metal pipelines and on the metal components of diverse equipment (rotary evaporators, freezedrying equipment, cooling traps ...
face-centered cubic (fcc) (cF4) Category: Lead. Lead (pronounced "led") is a chemical element; it has symbol Pb (from Latin plumbum) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point.
