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!
