Find the top three elements in the Earth’s crust ElementPercentage in the Earth’s crust Aluminium Calcium Iron Oxygen Silicon Sodium Others
Unit 4: What is Matter Made of?. Matter Pure Substances Mixtures Chemical Elements Chemical Compounds Homogeneus Mixtures Heterogeneus Mixtures Combining.
Lesson: Elements. Science Differentiation in action An element cannot be broken down into simpler substances by chemical means. Copper.
An Element is a simple substance that cannot be split up into simpler substances by chemical means.
A solution is a mixture that appears to be a single substance but is composed of particles of two or more substances that are distributed evenly.
H20 IS WATER. H20=2 parts hydrogen and 1 part oxygen.
Give the symbol for each element listed below. 1.Silicon 2.Uranium 3.Carbon 4.Magnesium 5.Sodium 6.Calcium 7.Hydrogen 8.Sulfur 9.Lead 10.Helium 11.Mercury.
Atoms and Elements. Atoms Atoms are the “building blocks” of all matter and are the simplest form of molecule. They are all made up of protons, neutrons.
Displacement reactions In a displacement reaction a more reactive element takes the place of a less reactive one in a compound.
Thermal Decomposition Reactions. Stable and Unstable Substances Stable in Chemistry means unreactive in the conditions stated. Unstable means reactive.
There are six main types of reactions Synthesis Decomposition Combustion Single Replacement (Single Displacement) Double Replacement (Double Replacement)
A pure substance: is made up of one sort of molecules (or atoms). A mixture: Is made up from more than one sort of molecules (atoms).
Lesson: Mixtures & Compounds. Science Differentiation in action A mixture is made of two or more substances mingled together but not chemically combined.
Complete the following slides using your notes from class and the internet. You MUST use your own words You should try to add images to go with.

Bromine Calcium Carbon Chlorine Cobalt Copper Gold Hydrogen Iodine Iron Lead Nitrogen Nickel Mercury Magnesium Aluminum Oxygen Phosphorus Silver Sodium.
Classification of Matter. Now that we have defined chemical and physical properties of matter, we can use that to help us classify it. One way chemists.
Acids… Learning objectives: Know that salts are formed from reactions with acids. Know how to write correct word equations. Know what salts are formed.
Elements All Elements are made from particles called atoms. Each element is made from a different type of atom. An atom is the smallest part of an element.
What do we call these things? 6 Atoms which happen to be of 3 different elements.
1. Atoms Elements Compounds 2. The structure of an Atom 3. Symbols for elements 4 Elements of the periodic table Chemistry Elements Chemistry Elements.
7 Elements. Every element has a unique set of properties.
Atoms, Molecules, Pure Substances, & Mixtures CRCT Prep Part I.
Week 4 Elements, Compounds, and Mixtures. Vocabulary element, pure substance, metal, non-metal, metalloid, compound, mixture, solution, solvent, solute,
Elements, mixtures and compounds. Elements Made up of only one kind of atom.
Intermediate 1 Unit 1a Substances
Lesson 11: Pure Substance or Mixture. Characteristic Properties An attribute that can be used to help identify a substance. A characteristic property.
Classifying Matter: Elements, Compounds, and Mixtures.
Understanding Solutions. What is a Solution? A solution is a well-mixed mixture. A solvent dissolves other substances. Example: water A solute is being.
Elements An element is a pure substance made of only 1 type of atom.
Classification of Matter. 1. Mixture – Two or more pure substances mixed together. Each substance in the mixture retains its own set of chemical and physical.
Classification of Matter Matter – anything that has mass and takes up space Pure Substance - matter that CANNOT be physically separated Compound – made.
Biochemistry. Basic Elements 99% of all living things are: Sulfur (S) Carbon (C) Hydrogen (H) Nitrogen (N) Oxygen (O) Phosphorus (P)

Classification of Matter Elements, Mixtures, and Compounds.
Atomic Structure. Lesson Objectives To know what is meant by an atom. To know that an atom is made up of three smaller particles. To be able to draw the.
Compounds Learning Goals: Differentiate between elements and compounds. Recognize that around 100 known elements exist that may be combined in nature or.
Elements, compounds and mixtures This quiz has 10 questions. For each question you have to decide if the statement is true or false. BEWARE ! One mistake.
DO NOW: Read Life depends on chemistry. When you eat food or inhale oxygen, your body uses these materials in chemical reactions that keep you alive. Just.
Types of Chemical Reactions We will study 4 types.
Grade 7 Science Solutions. Solutions… a review zA homogeneous mixture ie. they appear as ONE substance Examples: tap water, vinegar, gold jewelry, etc.
Classification of Matter Classification of Matter Now that we have defined what matter is, we can work on classifying matter into different.
Density Notes. What is density? Density – mass per unit volume What does per mean? – Examples that use per: miles per hour meters per second $ per pound.

Classifying Matter: Elements and Compounds. Matter Definition: – It has mass or weight – Takes up space (volume) Examples- anything; car, water, you,
Atoms and Elements. Chlorine Cl 2 Hydrogen chlorideHCl Methane CH 4 Carbon dioxide CO 2 Draw a line between the molecule and its name.
Done by: Sara Al-Khater 7D Science. The element is a substance that is made out from one type of atoms. element is a pure substance that cannot be.
Chapter 3 Types of Matter. 4 Types of Matter Heterogeneous vs Homogeneous Heterogeneous matter has more than one phase (it is not uniform throughout).
2.1 Notes: What is Matter? Main Idea 1: Chemistry is the study of the composition, structure, properties, and changes of matter.
