Substance Mixture Element Homogenous Mixture Compound

Heterogenous Mixture What is Matter? One or more atoms that take up space and has mass. Classification of Matter Lab Classification of Matter Lab

Elements Simplest class of matter that maintains its properties Purest class: composed of only one kind of atom. Each kind of atom is called an element. A symbol is used to represent each element. Compounds

Chemical combination of elements in a fixed amount or ratio. A compounds fixed ratio 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) 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. Heterogenous Mixures

Observe multiple phases (parts) because the substances do NOT mix well. Homogenous Mixtures Also called solutions Substances mix so well they look like one phase. 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 + H2O

mixture: homo mix Classifying Matter: Substances vs. Mixtures Substances Definite chemical make-up Elements or compounds

Ex. Silicon chip or H2O Mixtures Varied chemical makeup 2 or more substances physically combined Homo or Hetero Mixtures Pizza and salt water

Classifying Matter: Substances vs. Mixtures Element Homogenous Mixture Pure and simplest substance One type of atom

Periodic table Symbol, (He= Helium) 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, H2O 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 Chemistry: 1.11.17

Classifying Matter Classifying Matter: Micro Level Substances? Mixtures? Bell Ringer: Classifying Matter 1. What is the difference between:

a. a substance and a mixture? Give an example of each. b. a compound and a mixture? Give an example of each. Matter: Physical vs. Chemical Properties Physical Properties

Chemical Properties Matter: Physical vs. Chemical Properties Physical Properties Does not change the chemical make-up of the matter. Color, shape, mass, length, odor, states of

matter, solubility Chemical Properties Does change the chemical make-up of matter. flammable, neutralization, rusting,decomposing

Solubility How good one substance dissolves (physically mixes) with another substance. Salt added to water Soluble

Insoluble Soluble Solutions Solutions are composed of: Solute: what is dissolved in the solution.

substance you have less of Solvent: what dissolves the solute substance you have more of water is a common solvent Neutralization

Change in pH of a solution by the addition of an acid (H+ ions) or a base (OH- ion). Flammability and Combustion Matter that can catch on fire and produce a lot of energy. www.astm.org

Chem I: 1.17.17 Due: Physical vs. Chemical Properties/Change Worksheet Atomic Structure Ranking Task Worksheet Objectives: I can classify changes with matter as physical

or chemical. (Physical vs. Chemical Change Lab) I can apply intermolecular and intramolecular forces with changes that matter undergoes. Chemical vs. Physical Change Chemical Change: Physical Change:

Chemical vs. Physical Change Chemical Change: Matters chemical make-up changes. New matter is produced with new properties. Ex. Iron Rust (FeO) Physical Change: Physical properties change, but chemical properties are preserved.

Matters chemical make-up stays the same. Ex. cutting paper Matter and Forces Intramolecular Forces Intermolecular Forces

Intramolecular Forces Forces within a compound that hold the atoms together. (chemical bonds) Affected/altered during a chemical change. H2O compound Intermolecular Forces Forces between compounds in a sample of matter. (group forces)

Affected/altered during a physical change. Matter and Changes 1. Explain the difference between a matters physical property vs. a chemical property. Give an example of each. 2. Explain the difference between matter undergoing a physical change vs. a chemical change. Give an example of

each. Physical vs. Chemical Properties/Change Lab Goggles must be worn at all times or you will be dismissed from the lab-NO exceptions! Remember to record all observations. (needs to be legible and descriptive) Caution: Working with HCl acid, so be careful. Disposal of Materials: Most can be discarded

down drains except metal waste (Mg). Physical vs. Chemical Properties/Change Lab Conclusion: 1. Give an example from the lab where a physical change occurred. What evidence do you have to prove this was a physical change? 2. Give an example from the lab where a

chemical change occurred. What evidence do you have to prove this was a chemical change? Mixtures Substances in a mixture can be separated from one another through physical processes.

Some common methods to separate mixtures are: *Filtration *Extraction *Distillation *Chromatography Explain which methods you applied during the physical vs. chemical change lab?

Physical Separation Techniques Separation Techniques Filtration Extraction Distillation Chromatography Physical

property used for separation For homo or hetero mixtures Filtration

Separating a solid from a liquid in a heterogenous mixture by their size difference. Extraction 1. Extraction- separating substances in a heterogenous mixture from one another based on their unique physical properties. Sand and Iron Filings

Physical Separation of Mixtures Distillation Separation of liquids in a mixture by their differences in boiling points. Ex. Ethanol (78 0C) and Water (1000C) Chromatography Separates substances present within a homogenous mixture. Stationary phase

Usually in solid state: ex.chromotography paper Mobile Phase Liquid or gas solvent The two phases help separate substances in a homogenous mixture based on solubility. Conservation of Matter

Matter can go through physical and chemical changes, but the atoms are always conserved. Atomic Structure education.jlab.org

What do you predict the size difference is between an atoms nucleus and its electron Atomic Number The number of protons within an atoms nucleus. Its an atoms I.D.

Atoms of the same element always have the same number of protons. Do you notice any patterns with atomic numbers on the periodic table? Elements Atomic Numbers Mass Number Mass number :

The mass of a single atom. Sum of the p+ and n0 within an atom. Common unit: atomic mass unit (amu) *The mass number is NOT the same as atomic mass located on your periodic table. Subatomic Particles in an Atom Subatomic Particle

symbol charge location Mass (g) mass # (amu)

proton 1.674 x 10 -24 1 electron 9.11 x 10-28

neutron 1.675 x 10 -24 1 0 Ions Isotopes

Chem I:Isotopes 1. Calculate the protons, neutrons, and electrons in each set of isotopes and illustrate each isotope with correct location and number of subatomic particles. a. Li-6 and Li-7 b. H-1 and H-2 c. O-16 and O-17 d. B-10 and B-11

Chem I:Isotopes 1. Calculate the protons, neutrons, and electrons in each set of isotopes and illustrate each isotope with correct location and number of subatomic particles. a. Li-6 and Li-7 b. H-1 and H-2 c. O-16 and O-17 d. B-10 and B-11

Mass Number vs. Atomic Mass Mass number: An Atoms Mass Mass number : The mass of a single atom. Sum of the p+ and n0 within an atom. Common unit: atomic mass unit (amu) *The mass number is NOT the same as atomic

mass located on your periodic table. Calculating Atomic Mass of an Element Atomic mass: It is an average mass calculated from all the isotopes o a particular element. The average mass is weighted because there is NOT an equal amount of each isotope in a sample.

How do you calculate a weighted average mass? 1. For each isotope, multiply its mass (mass #) by its natural abundance (decimal form) to get the weighted mass for each isotope. 2. Add up the isotopes weighted masses to get the atomic mass (average mass) for the element. Calculating Atomic Mass Isotope

Natural Abundance (%) Kandium Lab Purpose: To investigate an new elements isotopes to calculate what its atomic mass is.
