  2. Alkaline earth metal - Wikipedia

    en.wikipedia.org/wiki/Alkaline_earth_metal

    Reaction with halogens. Ca + Cl 2 → CaCl 2. Anhydrous calcium chloride is a hygroscopic substance that is used as a desiccant. Exposed to air, it will absorb water vapour from the air, forming a solution. This property is known as deliquescence. Reaction with oxygen. Ca + 1/2O 2 → CaO Mg + 1/2O 2 → MgO. Reaction with sulfur. Ca + 1/8S 8 ...

  3. Group 2 organometallic chemistry - Wikipedia

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

    Group 2 organometallic chemistry refers to the organic derivativess of any group 2 element. It is a subtheme to main group organometallic chemistry. [2] [3] By far the most common group 2 organometallic compounds are the magnesium-containing Grignard reagents which are widely used in organic chemistry. Other organometallic group 2 compounds are ...

  4. Water-reactive substances - Wikipedia

    Group 1: Alkali metals Reaction of sodium (Na) and water Reaction of potassium (K) in water. The alkali metals (Li, Na, K, Rb, Cs, and Fr) are the most reactive metals in the periodic table - they all react vigorously or even explosively with cold water, resulting in the displacement of hydrogen.

  6. Organometallic chemistry - Wikipedia

    en.wikipedia.org/wiki/Organometallic_chemistry

    A steel bottle containing MgCp 2 (magnesium bis-cyclopentadienyl), which, like several other organometallic compounds, is pyrophoric in air.. Organometallic compounds are distinguished by the prefix "organo-" (e.g., organopalladium compounds), and include all compounds which contain a bond between a metal atom and a carbon atom of an organyl group. [2]

  7. Basic oxide - Wikipedia

    en.wikipedia.org/wiki/Basic_oxide

    Alkali metals (Group 1) X 2 O + H 2 O → 2XOH (X = group 1 element) Alkaline earth metals (group 2) XO + H 2 O → X(OH) 2 (X = group 2 element) For example, the basic oxide Li 2 O becomes the hydroxide LiOH, and BaO becomes Ba(OH) 2 after reacting with water. In contrast, non-metals usually form acidic oxides.

  8. Chemical reaction - Wikipedia

    en.wikipedia.org/wiki/Chemical_reaction

    For some main-group elements the number of electrons donated or accepted in a redox reaction can be predicted from the electron configuration of the reactant element. Elements try to reach the low-energy noble gas configuration, and therefore alkali metals and halogens will donate and accept one electron, respectively. Noble gases themselves ...

  9. Group (periodic table) - Wikipedia

    en.wikipedia.org/wiki/Group_(periodic_table)

    In the periodic table of the elements, each column is a group. In chemistry, a group (also known as a family) [1] is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the 14 f-block columns, between groups 2 and 3, are not numbered.
