    This document discusses elements and their properties. It defines an element as a substance that cannot be broken down further. Elements are made up of only one type of atom. Elements have distinct physical properties like luster, volume, color, mass and shape. They also have chemical properties such as flammability, oxidation, toxicity, acidity and stability. Common elements and their physical and chemical properties are discussed. The document also covers metals, nonmetals, semimetals and their characteristics.

    Elements
     An element is a substance that cannot be broken down
    into any other substance. Every element is made up of its
    own type of atom or made up of one type of atom.
    Iron Code: 479qtg
    Elements cannot be broken down into simpler ones by chemical
    means.

     Elements could either have physical and chemical properties. To show
    distinction of elements found either free in nature or artificial, here are some
    of its physical and chemical properties as pure substances.

    Physical Chemical
    Luster Flammability
    Volume Oxidation
    Color Toxicity
    Mass Acidity
    Shape Stability
    Physical Properties of Elements

    1. Luster-shiny in appearance
    2. Volume- amount of space occupied by an object
    3. Color-the aspect of the appearance of objects and light sources
    4. Mass-the amount of material it contains
    5. Shape-appearance or form of a sample matter
    Luster
    Color
    Chemical Properties of Elements
    1. Flammability-ability to be burnt easily or undergo combustion
    2. Oxidation-to be rusted or being oxidized and form oxides
    3. Toxicity-the relative degree of being poisonous
    4. Acidity-the state of being acidic by nature
    5. Stability-resistance to chemical change or to physical
    disintegration
    Flammability
    Toxicity
     1. mercury, Hg
     2. lead, Pb
     3. arsenic, As
     4. chlorine, Cl
    Stability
    Lithium (Li), sodium (Na) and potassium (K) are kept in mineral oil or kerosene to
    avoid exposure to air and moisture. Na, Li and K are very reactive to atmospheric
    oxygen in air and water vapor in air.
    Metals, Nonmetal and Semimetals
    Examples
    Malleability and Ducitility
    Metals are conductor of electricity and nonmetals are insulators
    Metals are good conductor of heat.
