Lead

Lead is a chemical element in the carbon group with symbol Pb (from Latin: plumbum) and atomic number 82. Lead is a soft, malleable poor metal. It is also counted as one of the heavy metals. Metallic lead has a bluish-white color after being freshly cut, but it soon tarnishes to a dull grayish color when exposed to air. Lead has a shiny chrome-silver luster when it is melted into a liquid.

Famous quotes containing the word lead:

    There was ... a large, shaggy dog, whose nose, report said, was full of porcupine quills. I can testify that he looked very sober. This is the usual fortune of pioneer dogs, for they have to face the brunt of the battle for their race.... When a generation or two have used up all their enemies’ darts, their successors lead a comparatively easy life. We owe to our fathers analogous blessings.
    Henry David Thoreau (1817–1862)

    “Yet let him keep the rest,
    But keep them with repining restlessness:
    Let him be rich and weary, that at least,
    If goodness lead him not, yet weariness
    May toss him to My breast.”
    George Herbert (1593–1633)

    Rule of art: let half-blind purpose lead you.
    Mason Cooley (b. 1927)
