72 D1.2 Elements make up the periodic table.

73 Different types of atoms are organized onto a chart. This chart is called the Periodic Table of Elements.

75 Elements can be organized by similarities The periodic table organizes the atoms of the elements by properties and atomic number row = “period” similar chemical properties

76 The periodic table has distinct regions.

77 Most elements are metals.

78 Nonmetals and metalloids have a wide range of properties.

79 Choose 3 colors. Make a key, of what each color stands for. Color the periodic table into 3 sections (as in this image):

152 What is the charge of an electron? What is an ion?

153 What is the charge of an electron? negative What is an ion? an atom with a (positive or negative) charge

154 What determines an ion’s charge? If an atom loses an electron, then it becomes less negative and has a positive charge. If an atom gains an electron, then it becomes more negative and has a negative charge.

156 MAGNETS! How’s it made, magnets Vinegar battery: Solar cell: Earth’s magnetic field: https://www.youtube.com/watch?v=izlqoHYZWqg https://www.youtube.com/watch?v=izlqoHYZWqg Ferrofluid:

157 Magnetic field: Magnets exhibit (show) positive and negative charges. This attraction forms a magnetic field. Gravity pulls electrons from one side of the magnet to the other side.

158 Vocabulary: magnetic field: invisible force that travels from positive to negative north pole: end of magnet that is positively charged south pole: end of magnet that is negatively charged

159 Rules for drawing magnetic field lines: 1. Arrows start at the (positively charged) north pole to (negatively charged) the south pole 2. Arrows should never cross 3. The closer the field lines are to each other, the stronger the magnet “Electrons travel from positive to negative.”

160 Vocabulary electricity: presence and motion of charged particles electric current: flow of electrons around a closed path (electric circuit) circuit: closed path on which electrons travel

161 Electric charge: there are two types of electric charges - positive and negative Like charges repel. Unlike charges attract.

162 conductor: a material through which electrons flow easily

163 insulator: a material that resists the flow of electrons

164 Let’s practice making more circuits!

165 The flow of electrons creates an electrical current.

166 How many circuit combinations can you make?
