Tin is a post-transition metal in group 14 of the periodic table of elements. It is obtained chiefly from the mineral cassiterite, which contains stannic oxide, SnO 2. Tin shows a chemical similarity to both of its neighbors in group 14, germanium and lead, and has two main oxidation states, +2 and the slightly more stable
Tin(IV) iodide, also known as stannic iodide, is the chemical compound with the formula SnI 4. This tetrahedral molecule crystallizes as a bright orange solid that dissolves readily in nonpolar solvents such as benzene .
Bismuth vanadate orange (PO86): non-toxic pigment similar to vermilion. Cadmium pigments. Cadmium orange (PO20): an intermediate between cadmium red and cadmium yellow: cadmium sulfoselenide. Chromium pigments. Chrome orange: a now obscure pigment composed of a mixture of lead chromate and lead(II) oxide (PbCrO 4 •PbO).
A study showed that 99.5% of the controlled food cans contain tin in an amount below that level. [4] However, un-lacquered tin cans with food of a low pH, such as fruits and pickled vegetables, can contain elevated concentrations of tin. [2] The toxic effects of tin compounds are based on its interference with iron and copper metabolism.
Freshly prepared aqua regia is colorless, but it turns yellow, orange or red within seconds from the formation of nitrosyl chloride and nitrogen dioxide. It was so named by alchemists because it can dissolve noble metals like gold and platinum , though not all metals.
Tin medal affected by tin pest. Tin pest is an autocatalytic, allotropic transformation of the element tin, which causes deterioration of tin objects at low temperatures. Tin pest has also been called tin disease, [1] tin blight, tin plague, [2] or tin leprosy. [3] It is an autocatalytic process, accelerating once it begins.

The UV-vis spectrum for a compound that appears orange in Dimethylformamide. All atoms and molecules are capable of absorbing and releasing energy in the form of photons, accompanied by a change of quantum state. The amount of energy absorbed or released is the difference between the energies of the two quantum states.
