Alkaline Earth Metal

Alkaline Earth Metal

The alkaline earth metals are a group of chemical elements in the periodic table with very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure and readily lose their two outermost electrons to form cations with charge +2. In the modern IUPAC nomenclature, the alkaline earth metals comprise the group 2 elements.

The alkaline earth metals are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). This group lies in the s-block of the periodic table as all alkaline earth metals have their outermost electron in an s-orbital.

All the discovered alkaline earth metals occur in nature. Experiments have been conducted to attempt the synthesis of unbinilium (Ubn), which is likely to be the next member of the group, but they have all met with failure. However, unbinilium may not be an alkaline earth metal due to relativistic effects, which are predicted to have a large influence on the chemical properties of superheavy elements.

Famous quotes containing the words metal and/or earth:

    There were metal detectors on the staff-room doors and Hernandez usually had a drawer full of push-daggers, nunchuks, stun-guns, knucks, boot-knives, and whatever else the detectors had picked up. Like Friday morning at a South Miami high school.
    William Gibson (b. 1948)

    And what is so rare as a day in June?
    Then, if ever, come perfect days;
    Then Heaven tries earth if it be in tune,
    And over it softly her warm ear lays:
    Whether we look, or whether we listen,
    We hear life murmur, or see it glisten;
    James Russell Lowell (1819–1891)
