Notebook Check Test 2 24-25

Master periodic table trends, classify elements, and practice density calculations!

Using your PTE Trends Notes for Metals, Metalloids and Nonmetals, sort the following into the correct categories. Metals left of the zig zag line malleable luster Metalloids touching the zig zag line kinda like metals semi conductors Nonmetals right of the zig zag line dull most are gases at room temp. Using the Periodic Table Trends PERIODS practice in your notebook, match the following. Element in period 2 with 10 neutrons Fluorine This element is in period 5 with 47 electrons. Silver Located in period 7 and has an atomic number of 98. Californium Does not have the same properties as sodium(Na). Chlorine What color was used in your notebook to highlight a family on the periodic table? (Trends cont'd Groups, Families, Columns) Red Orange Yellow Green If an element is in period 6 on the PTE, what do you know about the atomic structure of this element? The number of protons. The number of energy levels or shells. The number of valence electrons in the last shell. The atomic mass. I am looking for a family of INERT elements. What family is this? Alkali Mettals Alkaline Earth Metals Halogens Noble Gases Color, Shape, and Odor are chemical properties of substances. TRUE FALSE The apple slice from class, that was not exposed to lemon juice, turned an unexplained brown color. This was caused by a chemical property known as oxidation. TRUE FALSE A mystery substance has a mass of 148g and a volume of 40.0 cm3Its identity can be determined by calculating its density. 5920g 3.70g 108g 188g Calculate the volume of a liquid with a density of 1.82g and a mass of 30.0g. 0.06 mL 54.6 mL 28.18 mL 16.5 mL
