Group 12 Element

A group 12 element is one of the elements in group 12 (IUPAC style) in the periodic table. This includes zinc (Zn), cadmium (Cd) and mercury (Hg). The further inclusion of copernicium (Cn) in group 12 is supported by recent experiments on individual copernicium atoms. Group 12 is sometimes also known as the volatile metals, although this can also more generally refer to any metal that has high volatility, such as polonium or flerovium.

The three group 12 elements that occur naturally are zinc, cadmium and mercury. They are all widely used in electric and electronic applications, as well as in various alloys. The first two members of the group share similar properties as they are solid metals under standard conditions. Mercury is the only metal that is a liquid at room temperature. While zinc is very important in the biochemistry of living organisms, cadmium and mercury are both highly toxic. As copernicium does not occur in nature, it has to be synthesized in the laboratory.

Famous quotes containing the words group and/or element:

    Even in harmonious families there is this double life: the group life, which is the one we can observe in our neighbour’s household, and, underneath, another—secret and passionate and intense—which is the real life that stamps the faces and gives character to the voices of our friends. Always in his mind each member of these social units is escaping, running away, trying to break the net which circumstances and his own affections have woven about him.
    Willa Cather (1873–1947)

    The reverence for the Scriptures is an element of civilization, for thus has the history of the world been preserved, and is preserved.
    Ralph Waldo Emerson (1803–1882)
