Zinc compounds are chemical compounds containing the element zinc which is a member of the group 12 of the periodic table. The oxidation state of zinc in most compounds is the group oxidation state of +2. Zinc may be classified as a post-transition main group element with zinc(II). Zinc compounds are noteworthy for their nondescript appearance ...
Roughly one quarter of all zinc output in the United States (2009) is consumed in the form of zinc compounds, a variety of which are used industrially. [ 92 ] Cadmium has many common industrial uses as it is a key component in battery production, is present in cadmium pigments , [ 102 ] coatings, [ 90 ] and is commonly used in electroplating ...
The vast majority of compounds, including all aluminium-containing minerals and all commercially significant aluminium compounds, feature aluminium in the oxidation state 3+. The coordination number of such compounds varies, but generally Al 3+ is either six- or four-coordinate. Almost all compounds of aluminium(III) are colorless. [2]
The most common form of crystalline aluminium oxide is known as corundum, which is the thermodynamically stable form. [16] The oxygen ions form a nearly hexagonal close-packed structure with the aluminium ions filling two-thirds of the octahedral interstices.
Almost all zinc compounds have the element in the +2 oxidation state. [54] When Zn 2+ compounds form, the outer shell s electrons are lost, yielding a bare zinc ion with the electronic configuration [Ar]3d 10. [55] The filled interior d shell generally does not participate in bonding, producing diamagnetic and mostly colorless compounds. [53]
Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al 3+ is small and highly charged; as such, it has more polarizing power, and bonds formed by aluminium have a more covalent character. The strong affinity of ...
This complements alternative listing at list of inorganic compounds. There is no complete list of chemical compounds since by nature the list would be infinite. Note: There are elements for which spellings may differ, such as aluminum/aluminium, sulfur/sulphur, and caesium/cesium.
Zinc hydroxide Zn 2 is an inorganic chemical compound. It also occurs naturally as 3 rare minerals: wülfingite (orthorhombic), ashoverite and sweetite (both tetragonal). Like the hydroxides of other metals, such as lead , aluminium , beryllium , tin and chromium , Zinc hydroxide (and Zinc oxide ), is amphoteric .
