Presentation Transcript

  1. A Mad Scientist’s Chemistry Presentation Laws of Definite & Multiple proportion

  2. Molecules: A quick review • Molecules are the smallest electrically neutral unit. • Monatomic molecules are the Noble Gases. • HONClBrIF are the diatomic molecules. • Molecules are made of 2 or more atoms sharing electrons. • Non metal & non metal

  3. Ionic Compounds • Ionic compounds are made up of groups of charged particles. • Cations and Anions • The smallest neutral unit of the resulting crystal is called a Formula Unit. • Metal and non metal

  4. Law of Definite Proportion

  5. Law of Multiple Proportions • Whenever two or more elements form more than one compound, different masses form with the same mass of another element in simple whole number ratios

  6. You have 2 H for each 1 O in water What does that mean? The Mad Scientist But: You have 2 H for every 2 O in hydrogen peroxide.

  7. Does that apply for Both? • The Laws of Multiple and Definite Proportions apply to both Ionic and Covalent Compounds.
