3
What is Matter? One or more atoms that take up space and has mass.
4
Classification of Matter-2nd
5
Classification of Matter-3rd
6
Classification of Matter-6th
7
Elements Simplest substance
8
Compounds Chemical combination of elements in a fixed amount (always the same way). A compound’s fixed amount is called a chemical formula. Ex. Sodium chloride = NaCl When elements chemically combine the compound produced has new properties. Sodium (Na) + Chlorine (Cl) = Salt (NaCl)
9
Mixture Substances (elements or compounds) are physically mixed together to produce a mixture. The composition of substances in a mixture varies from one sample to another. The physical properties of each substance in a mixture is preserved.
10
Heterogenous Mixures Observe multiple phases (parts) because the substances do NOT mix well.
11
Homogenous Mixtures Also called solutions Substances mix so well they look like one phase.
12
Substances in Matter The symbol/formula for matter identifies Kind and number of substances in matter Identifies class of matter Sodium: Na Element Salt: NaCl Compound Salt Water: NaCl + H 2 O mixture: homo mix
13
Classifying Matter: Substances vs. Mixtures Substances Definite chemical make-up Elements or compounds Ex. Silicon chip or H 2 O Mixtures Varied chemical make- up 2 or more substances physically combined Homo or Hetero Mixtures Pizza and salt water
14
Classifying Matter: Substances vs. Mixtures Element Pure and simplest substance One type of atom Periodic table Symbol, (He= Helium) Homogenous Mixture 2 or more substances physically combined. Substances are very soluble in one another-mix well – one phase Substances in mix properties are preserved Separated by physical processes. Also called a solution Ex. salt water, kool-aid Compound 2 or more substances chemically combined Definite composition Break-down only thru chemical processes Substances making up cmpd gain new properties. Chemical Formula, H 2 O Ex. iron rust Heterogenous Mixture 2 or more substances physically combined. Substances are not soluble in one another-do not mix well-multiple phases Substances in mixture properties are preserved. Separated by physical processes Ex. Oil and water, pizza, soil
