  2. Light metal - Wikipedia

    en.wikipedia.org/wiki/Light_metal

    Lithium and then potassium are the two lightest metallic elements. Magnesium, aluminium and titanium alloys are light metals of significant commercial importance. [2] Their densities of 1.7, 2.7 and 4.5 g/cm 3 range from 19 to 56% of the densities of other structural metals, [3] such as iron (7.9) and copper (8.9).

  3. List of elements by stability of isotopes - Wikipedia

    en.wikipedia.org/wiki/List_of_elements_by...

    An even number of protons or neutrons is more stable (higher binding energy) because of pairing effects, so even–even nuclides are much more stable than odd–odd. One effect is that there are few stable odd–odd nuclides: in fact only five are stable, with another four having half-lives longer than a billion years.

  4. Lithium - Wikipedia

    en.wikipedia.org/wiki/Lithium

    It is the least dense of all elements that are solids at room temperature; the next lightest solid element (potassium, at 0.862 g/cm 3) is more than 60% denser. Apart from helium and hydrogen , as a solid it is less dense than any other element as a liquid, being only two-thirds as dense as liquid nitrogen (0.808 g/cm 3 ). [ 15 ]

  6. 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.

  7. Magnesium alloy - Wikipedia

    en.wikipedia.org/wiki/Magnesium_alloy

    Figure 1: Number of scientific articles with terms AZ91 or AZ31 in the abstract. Camera chassis of a Samsung NX1, made of magnesium alloy. Magnesium alloys are mixtures of magnesium (the lightest structural metal) with other metals (called an alloy), often aluminium, zinc, manganese, silicon, copper, rare earths and zirconium.

  8. Titanium alloys - Wikipedia

    en.wikipedia.org/wiki/Titanium_alloys

    Titanium alloys have been extensively used for the manufacturing of metal orthopedic joint replacements and bone plate surgeries. They are normally produced from wrought or cast bar stock by CNC, CAD-driven machining, or powder metallurgy production. Each of these techniques comes with inherent advantages and disadvantages.
