21-2 Unit 3: Test Review (Density, Metals, Physical Properties)

Master density, metals, and the periodic table! Practice key science concepts.

Where are METALS, NONMETALS, and METALLOIDS found on the Periodic Table of Elements? Label each section of the Periodic Table of Elements by typing the following terms (plural, all capitals):METALS, NONMETALS, METALLOIDS. NONMETALS METALLOIDS METALS Choose the examples of metals, nonmetals, and metalloids and sort them into the appropriate columns. Using the Periodic Table of Elements (above), sort the following ELEMENTS into the appropriate columns. metals Na (Sodium) Au (Gold) nonmetals Ne (Neon) O (Oxygen) metalloids Si (Silicon) As (Arsenic) malleability ability to shape (into thin sheet) brittleness ability to crumble into powder luster ability to reflect light ductility ability to shape in a wire conductor able to let heat through metals good conductors (++) metallic luster ductile dented by hammer (malleable) nonmetals insulators (-) brittle dull often gases metalloids semiconductors poor conductors (+) may have luster dull somewhat malleable Identifying Unknown Substances Using Density Substance A has 200g 4ml, Substance B has 30ml 20g, Substance C has 60g 30ml.We know Krypton has the highest density, Slime has the lowest, Oobleck is in between Krypton and Slime.Record the missing Substance Names in the Table below. SUBSTANCE LETTER Density (g Substance Name A 50 Krypton B 0.07 Slime C 2 Oobleck Which of these is FALSE about a physical model of a solar system? a limitation might be that it is not to scale (wrong proportions) an advantage might be that you can see details of whole solar system in one model a limitation is that the model is more expensive than a space trip an advantage is that it is easy to store and transport What is the density of the chalk if the following readings are noted: 10 g 0.07 g 142 g 14.2 g Which of the following statements is true about the image shown below? volumes are same masses are same densities are same none of these statements are true Calculate the densities of the liquids in the density column and then choose the response that best lists the substances from the lowest to the highest densities.Dawn soap: 10ml 10.3g; lamp oil: 12g 15ml; vegetable oil: 15ml 13.8g; honey: 14.5g 10ml honey, Dawn, vegetable oil, lamp oil lamp oil, vegetable oil, Dawn, honey Dawn, honey, lamp oil, vegetable oil lamp oil, honey, Dawn, vegetable oil Determine which of the substance from the table below is described by a substance that has 12 g and 8 ml. cement silver H2O (water) foil (aluminum) Look at the image below. Identify which of the statement(s) below are true about the image. the masses of the cubes are the same the volumes of the cubes are the same the densities of the cubes are different the densities of the cubes are the same To mark a word click its first letter then click its last.
