Germanium is a lustrous, hard, grayish-white metalloid in the carbon group, chemically similar to its group neighbors tin and silicon. By mass, aluminium makes up about 8% of the Earth’s crust; it is the third most abundant element after oxygen and silicon and the most abundant metal in the crust, though it is less common in the mantle below. This helps to create a hydrophobic pocket on the enzyme near the zinc, which attracts the non-polar part of the protein being digested. [133], Zinc powder is sometimes used as a propellant in model rockets. Man-made and natural emissions occur at a ratio of 20 to 1. [224], Zinc deficiency appears to be the most common micronutrient deficiency in crop plants; it is particularly common in high-pH soils.

Zinc levels of 2000 ppm to 180,000 ppm (18%) have been recorded in some soil samples. Like all elements with atomic number over 100, nobelium can only be produced in particle accelerators by bombarding lighter elements with charged particles. [107][note 2] Zinc is also used to cathodically protect metals that are exposed to sea water. Therefore, the element or ion that is oxidized undergoes an increase in oxidation number. [89] About 70% of the world's zinc originates from mining, while the remaining 30% comes from recycling secondary zinc. This is because oxygen always has an oxidation number of -2. It is a member of the chalcogen group on the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds.

The chemical symbol for Aluminum is Al. [217] While zinc deficiency is usually due to insufficient dietary intake, it can be associated with malabsorption, acrodermatitis enteropathica, chronic liver disease, chronic renal disease, sickle cell disease, diabetes, malignancy, and other chronic illnesses. [99][170], In proteins, zinc ions are often coordinated to the amino acid side chains of aspartic acid, glutamic acid, cysteine and histidine. [188], In vertebrate blood, carbonic anhydrase converts CO2 into bicarbonate and the same enzyme transforms the bicarbonate back into CO2 for exhalation through the lungs. Balance the charge, using either H + (if in ACID solution) or OH-(if in BASE solution). [156], Zinc deficiency may lead to loss of appetite.

[9][169] It interacts with "a wide range of organic ligands",[9] and has roles in the metabolism of RNA and DNA, signal transduction, and gene expression. Zinc oxide is widely used as a white pigment in paints and as a catalyst in the manufacture of rubber to disperse heat. The commercial use of beryllium requires the use of appropriate dust control equipment and industrial controls at all times because of the toxicity of inhaled beryllium-containing dusts that can cause a chronic life-threatening allergic disease in some people called berylliosis. Tellurium is chemically related to selenium and sulfur. Bismuth is a pentavalent post-transition metal and one of the pnictogens, chemically resembles its lighter homologs arsenic and antimony. Excess zinc is toxic to plants, although zinc toxicity is far less widespread. Lead has the highest atomic number of any stable element and concludes three major decay chains of heavier elements. Technetium is the lightest element whose isotopes are all radioactive; none are stable. [150] Generally, zinc supplement is recommended where there is high risk of zinc deficiency (such as low and middle income countries) as a preventive measure. [122], As a dense, inexpensive, easily worked material, zinc is used as a lead replacement. [83], William Champion's brother, John, patented a process in 1758 for calcining zinc sulfide into an oxide usable in the retort process. Francium is the second-least electronegative element, behind only caesium, and is the second rarest naturally occurring element (after astatine). The pills were used for sore eyes and were found aboard the Roman ship Relitto del Pozzino, wrecked in 140 BC. The smelting of metallic zinc here, however, appears to have begun around the 12th century AD. [134] When a compressed mixture of 70% zinc and 30% sulfur powder is ignited there is a violent chemical reaction. Zinc is the primary metal in American one cent coins (pennies) since 1982.
