  2. Category:Bromides - Wikipedia

    en.wikipedia.org/wiki/Category:Bromides

    This category is limited to chemical compounds which contain inorganic bromine in a -1 oxidation state. These may be metal salts containing bromide ion such as potassium bromide, or more covalent bromides of metals or nonmetals such as tantalum(V) bromide or phosphorus tribromide.

  3. Bromine - Wikipedia

    en.wikipedia.org/wiki/Bromine

    Most metal bromides with the metal in low oxidation states (+1 to +3) are ionic. Nonmetals tend to form covalent molecular bromides, as do metals in high oxidation states from +3 and above. Both ionic and covalent bromides are known for metals in oxidation state +3 (e.g. scandium bromide is mostly ionic, but aluminium bromide is not).

    Liquid bromine. Bromine is a deep brown diatomic liquid that is quite reactive, and has a liquid density of 3.1028 g/cm 3. It boils at 58.8 °C and solidifies at −7.3 °C to an orange crystalline solid (density 4.05 g/cm −3). It is the only element, apart from mercury, known to be a liquid at room temperature.

    en.wikipedia.org/wiki/Bromine_compounds

    Most of the bromides of the pre-transition metals (groups 1, 2, and 3, along with the lanthanides and actinides in the +2 and +3 oxidation states) are mostly ionic, while nonmetals tend to form covalent molecular bromides, as do metals in high oxidation states from +3 and above.

  6. Nonmetal - Wikipedia

    en.wikipedia.org/wiki/Nonmetal

    Covalent nonmetals existing as discrete atoms like xenon, or as small molecules, such as oxygen, sulfur, and bromine, have low melting and boiling points; many are gases at room temperature, as they are held together by weak London dispersion forces acting between their atoms or molecules, although the molecules themselves have strong covalent ...

  7. Bromide - Wikipedia

    en.wikipedia.org/wiki/Bromide

    A bromide ion is the negatively charged form (Br −) of the element bromine, a member of the halogens group on the periodic table.Most bromides are colorless. Bromides have many practical roles, being found in anticonvulsants, flame-retardant materials, and cell stains. [3]

  8. Properties of metals, metalloids and nonmetals - Wikipedia

    en.wikipedia.org/wiki/Properties_of_metals...

    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.

  9. Nonmetallic material - Wikipedia

    en.wikipedia.org/wiki/Nonmetallic_material

    Nonmetals have a wide range of properties, for instance the nonmetal diamond is the hardest known material, while the nonmetal molybdenum disulfide is a solid lubricants used in space. [47] There are some properties specific to them not having electrons at the Fermi energy.
