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

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

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

Law of Definite Proportion

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

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

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