1 9 Weeks Review Compared to nonmetals, what periodic trends do metals tend to have? It has been raining for several days. Overnight, the temperature dropped below t he freezing point. Travel is now hazardous due to ice forming on the roadways. This is an example of a -- physical change chemical change physical property chemical property Which state of matter has the greatest amount of kinetic energy? An object is observed to have a silver color and a metallic appearance. The obj ect is also found to have a mass of grams and melts at C. Of the observed properties listed above,which is considered to be an extensive property? Which of the following is a correct statement regarding mixtures? Mixtures are composed of more than one substance. Mixtures have a fixed composition. Mixtures are composed of a single substance. All substances in a mixture are visible at all times. How many valence electrons are in Group 2? Which model showed electrons in specific, fixed orbits?
2 Which family correctly represents the elements in Group 1 on the Periodic Table? Using the Periodic Table, predict which elements will have similar chemical prop erties or reactivity. Rubidium, yttrium, and zirconium Nitrogen, sulfur, and bromine Magnesium, strontium, and barium Cadmium, calcium, and carbon An isotope of mercury has 80 protons and 120 neutrons. What is the mass of thi s isotope? In 1869, Mendeleev created a periodic table in which elements were ordered by atomic weight and placed in groups based on their chemical properties. Mendeleev's decision to design the periodic table in this way allowed immediate advances in chemistry by which of the following statements? -Provided an explanation for the reactive properties of the alkali metals. -By predicting the properties of undiscovered elements in specific atomic weight ranges. -By providing a framework for models of electron configurations. -By predicting the existence of a group of undiscovered inert gases. Name the chemical properties of Sodium When sulfuric acid is combined with sugar, gas is released and a tall, black column forms. This is an example of a physical property chemical property
3 physical change chemical change What are the characteristics of sulfur? As the atomic number on the Periodic Table increases, what happens to the number of electrons? Describe the trend of ionic energies or atomic radii in the Periodic Table In which section of the Periodic Table are the most active metals located A brand of balsamic vinaigrette salad dressing is a red liquid that is consistent throughout in color and texture with an ingredients list that includes water and acetic acid. Based on the information provided, how should the balsamic vinaigrette be classified? Balsamic vinaigrette is a heterogeneous mixture. Balsamic vinaigrette is a homogeneous mixture. Balsamic vinaigrette is a pure substance. Balsamic vinaigrette is a compound. Describe the chemical properties of oxygen? 1.
