Element of the Day - Friday, May, 21

Who am I? I am a dull, bluish-gray, non-magnetic metal. I am the fourth most common metal in use and am used to coat steel to prevent rust and corrosion. I am also used in the alloy brass. In addition, I am used in some batteries and compounds of me are also used in deodorants and sunscreens. Small amounts of me are necessary for the human body. Pennies made after 1981 are made of of mostly me with just a thin copper coating.
