CHEM 101 1st Edition Lecture 1Outline of Current LectureI. Introduction to MatterII. Introduction to Compounds Current LectureIII. Particles: Is a term used to refer to atoms, molecules or ionsIV. Matter: Anything that has mass and occupies spacea. There are 3 primary states of matter:i. Solid: Particles of solids are uniform and closely packed to one another. Their position does not change. Particles of solids move or vibrate to a degree unless the object in question is frozen. Volume and shape are constant. When solids are heated the particles gain energy and the solid becomes a liquid.ii. Liquid: Particles of liquids are farther apart than those seen in solids but still relatively close to one another. There is no fixed arrangement of particles and they can occupy any location in the object as there is more allowance for movement. Liquids conform to the containers that hold them.When you heat a liquid it becomes a gas because you energize and excite the particles. Freeze it and it will deplete particle energy to form a solid. iii. Gas: Characterized by large gaps between particles that are moving freely at high speeds. Gas can be compressed- unlike solids or liquids because ofthe space between particles in this state. Particles are in constant motion however they never average a speed. Particles move quickly because theycontain energy. Like liquids, gas conforms to the container it is in. V. Atom: the smallest unit of an element that retains all of the properties of that element.VI. Pure Substances: is any form of matter that has a uniform composition and cannot be separated by physical methods (i.e. filtration or evaporation). a. Elements and Compounds are 2 subclasses of pure substancesVII. Element: the simplest form of a molecular compound.VIII. Compounds: a substance made up of atoms from 2 or more elements.a. There are 2 broad categories of compounds: Molecular and Ionici. Molecules are the simplest units of a molecular compound.ii. A formula unit is the simplest unit of an ionic compound.b. The type of compound a substance is depends on the type of bond present.These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.c. Important to keep in mind** the elements that make up either type of compound cannot be separated by physical methods, but only by a chemical
