Slide 1: Chemistry Slide 2: Matter Matter = any material substance with Mass & Volume Slide 3: Matter comes in 3 phases Slide 4: Solid Definite Shape Definite Volume Slide 5: Liquid Indefinite Shape – takes the shape of the container Definite Volume Slide 6: Gas Indefinite Shape – takes the shape of the container Indefinite Volume – can expand and be compressed Slide 7: Elements one of the 100+ pure substances that make up everything in the universe Slide 8: Examples of Elements Slide 9: Atom the smallest particle making up elements Slide 10: Sub-atomic Particles Protons p+ - positive charge, in nucleus Electrons - e- negative charge, orbiting nucleus Neutrons n0 – no charge, in nucleus Slide 11: Drawing an Atom of Carbon minus Atomic # = # of n0 = # of p+ and # of e- Carbon has 6 p+ and 6 e- Carbon has 6 n0 Slide 12: Drawing an Atom of Carbon Slide 13: Compounds Compounds - 2 or more elements chemically combined to form a new substance with new properties Properties – The way a chemical substance looks and behaves Slide 14: Compounds Compounds – are made of 2 or more different atoms combined to form Molecules Chemical formula lists the number of different atoms in a single molecule Structural formula shows the arrangement of the atoms in a single molecule Slide 15: Molecules Glucose Sugar Slide 16: Compounds usually don’t contain Carbon
generally come from the earth
generally simple molecules always contain C & H and usually O, N, sometimes S & P
originate in organisms
generally complex molecules Slide 17: Examples of Inorganic Compounds Slide 18: Examples of Organic Compounds Slide 19: Chemistry Diga, diga, diga, diga, that’s all folks! Slide 20: This powerpoint was kindly donated to www.worldofteaching.com
