  3. 3. ELEMENTS
  4. 4. DEFINATIONS <ul><li>An element is a substance which cannot be split up into two or more simpler substances by the usual chemical methods of applying heat, light or electric energy. </li></ul><ul><li>An element is a substance which is made up of only one kind of atoms. </li></ul><ul><li>Every substance in this world is made up of one or more elements. </li></ul>
  5. 5. EXAMPLES <ul><li>SODIUM </li></ul><ul><li>DIAMOND </li></ul><ul><li>CARBON </li></ul><ul><li>MERCURY </li></ul><ul><li>BROMINE </li></ul><ul><li>HYDROGEN </li></ul><ul><li>OXYGEN </li></ul>
  6. 6. COMPOUNDS
  7. 7. DEFINATIONS <ul><li>A compound is a substance made up of two or more elements chemically combined in a fixed proportion by mass. </li></ul><ul><li>Compounds can be further divided into three classes on the basis of their properties: </li></ul><ul><li>a ) Acids </li></ul><ul><li>b ) Bases </li></ul><ul><li>c ) Salts </li></ul><ul><li>A compound cannot be separated into its components by physical methods. </li></ul><ul><li>The properties of a compounds are entirely different from those of its constituent elements. </li></ul><ul><li>The composition of a compound is fixed, the constituents are present in a fixed proportion by mass. </li></ul><ul><li>A compound has a fixed melting point, boiling point, etc. </li></ul><ul><li>Compound is a homogenous substance. </li></ul>
  8. 8. EXAMPLES <ul><li>Marble </li></ul><ul><li>Sodium Hydroxide </li></ul><ul><li>Common Salt </li></ul><ul><li>Water </li></ul><ul><li>Chalk </li></ul><ul><li>Copper Sulphate </li></ul>
  9. 9. MIXTURES
  10. 10. DEFINATIONS <ul><li>A mixture is a substance ehich consists of two or more elements or compounds not chemically combined together. </li></ul><ul><li>All solutions are mixtures. </li></ul><ul><li>The various substances present in a mixture are known as “constituents of mixture” or “components of the mixture”. </li></ul><ul><li>Mixtures are of two types: </li></ul><ul><li>a) Homogenous Mixtures </li></ul><ul><li>b) Heterogeneous Mixtures </li></ul>
  11. 11. Homogenous Mixtures <ul><li>Those mixtures in which the substances are completely mixed together and are indistinguishable from one another are called homogenous mixtures. </li></ul><ul><li>All the homogenous mixtures are called solutions. </li></ul><ul><li>Eg.. Sea water, Soft drinks, Air, Petrol, etc. </li></ul>
  12. 12. Heterogeneous Mixtures <ul><li>Those mixtures in which the substances remain separate and one substance is spread throughout the other substance as small particles, droplets or bubbles, are called heterogeneous mixtures. </li></ul><ul><li>The suspension of solids in liquids are also heterogeneous mixture. </li></ul><ul><li>A mixture containing two (or more) immiscible liquids is also a heterogeneous mixture. </li></ul><ul><li>Eg.. Glass, Soil, Milk, Ink, etc. </li></ul>
