  2. Aluminium compounds - Wikipedia

    en.wikipedia.org/wiki/Aluminium_compounds

    Aluminium's electropositive behavior, high affinity for oxygen, and highly negative standard electrode potential are all more similar to those of scandium, yttrium, lanthanum, and actinium, which have ds 2 configurations of three valence electrons outside a noble gas core: aluminium is the most electropositive metal in its group.

  3. Nitrogen compounds - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_compounds

    The chemical element nitrogen is one of the most abundant elements in the universe and can form many compounds. It can take several oxidation states; but the most common oxidation states are -3 and +3. Nitrogen can form nitride and nitrate ions. It also forms a part of nitric acid and nitrate salts.

  4. Aluminium(I) compounds - Wikipedia

    en.wikipedia.org/wiki/Aluminium(I)_compounds

    When reacted with transition metal-cyclopentadienyl complexes such as NiCp 2, it offers a straightforward pathway to compounds containing aluminium-transition metal bonds, which has great potential for important catalytic reactions. [2] NiCp 2 and AlCp* react to form a butterfly structure. The LUMO orbitals of CO are shown here.

  5. Alkali metal - Wikipedia

    en.wikipedia.org/wiki/Alkali_metal

    Lithium, the lightest of the alkali metals, is the only alkali metal which reacts with nitrogen at standard conditions, and its nitride is the only stable alkali metal nitride. Nitrogen is an unreactive gas because breaking the strong triple bond in the dinitrogen molecule (N 2) requires a lot of energy.

  6. Aluminium oxynitride - Wikipedia

    en.wikipedia.org/wiki/Aluminium_oxynitride

    Aluminium oxynitride (marketed under the name ALON by Surmet Corporation [3]) is a transparent ceramic composed of aluminium, oxygen and nitrogen.Aluminium oxynitride is optically transparent (≥80% for 2 mm thickness) in the near-ultraviolet, visible, and mid-wave-infrared regions of the electromagnetic spectrum.

  7. Aluminium - Wikipedia

    en.wikipedia.org/wiki/Aluminium

    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.

  8. Period 3 element - Wikipedia

    en.wikipedia.org/wiki/Period_3_element

    A period 3 element is one of the chemical elements in the third row (or period) of the periodic table of the chemical elements.The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behavior of the elements as their atomic number increases: a new row is begun when chemical behavior begins to repeat, meaning that elements with similar behavior fall into ...

  9. Aluminium hydride - Wikipedia

    en.wikipedia.org/wiki/Aluminium_hydride

    Aluminium hydride (also known as alane and alumane) refers to a collection of inorganic compounds with the formula Al H 3. As a gas, alane is a planar molecule. When generated in ether solutions, it exists as an ether adduct. Solutions of alane polymerizes to a solid, which exists in several crystallograhically distinguishable forms. [1]
