  2. Alkaline earth metal - Wikipedia

    en.wikipedia.org/wiki/Alkaline_earth_metal

    The heavier alkaline earth metals react more vigorously than the lighter ones. [2] The alkaline earth metals have the second-lowest first ionization energies in their respective periods of the periodic table [4] because of their somewhat low effective nuclear charges and the ability to attain a full outer shell configuration by losing just two ...

  3. Water-reactive substances - Wikipedia

    en.wikipedia.org/wiki/Water-reactive_substances

    Group 2: Alkaline earth metals. The alkaline earth metals (Be, Mg, Ca, Sr, Ba, and Ra) are the second most reactive metals in the periodic table, and, like the Group 1 metals, have increasing reactivity with increasing numbers of energy levels. Beryllium (Be) is the only alkaline earth metal that does not react with water or steam, even if the ...

  4. Alkali - Wikipedia

    en.wikipedia.org/wiki/Alkali

    A basic salt of an alkali metal or alkaline earth metal [2] (this includes Mg(OH) 2 (magnesium hydroxide) but excludes NH 3 ). Any base that is soluble in water and forms hydroxide ions [3] [4] or the solution of a base in water. [5] (This includes both Mg(OH) 2 and NH 3, which forms NH 4 OH.) The second subset of bases is also called an ...

  5. Radium - Wikipedia

    en.wikipedia.org/wiki/Radium

    Radium is the heaviest known alkaline earth metal and is the only radioactive member of its group. Its physical and chemical properties most closely resemble its lighter congener, barium. [4] Pure radium is a volatile, lustrous silvery-white metal, even though its lighter congeners calcium, strontium, and barium have a slight yellow tint. [4]

  6. Reactivity series - Wikipedia

    en.wikipedia.org/wiki/Reactivity_series

    Cs > K > Na > Li > alkaline earth metals, i.e., alkali metals > alkaline earth metals, the same as the reverse order of the (gas-phase) ionization energies. This is borne out by the extraction of metallic lithium by the electrolysis of a eutectic mixture of lithium chloride and potassium chloride: lithium metal is formed at the cathode, not ...

  7. Alkali metal - Wikipedia

    en.wikipedia.org/wiki/Alkali_metal

    While most metals form arsenides, only the alkali and alkaline earth metals form mostly ionic arsenides. The structure of Na 3 As is complex with unusually short Na–Na distances of 328–330 pm which are shorter than in sodium metal, and this indicates that even with these electropositive metals the bonding cannot be straightforwardly ionic. [10]

  8. Group 2 organometallic chemistry - Wikipedia

    en.wikipedia.org/wiki/Group_2_organometallic...

    As the group 2 elements (also referred to as the alkaline earth metals) contain two valence electrons, their chemistries have similarities group 12 organometallic compounds. Both readily assume a +2 oxidation states with higher and lower states being rare, and are less electronegative than carbon.
