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
