Section 3.4 and 3.5 Period 4 Group 8 http://lightwavebiomat.com/images/ne gIons.jpg What a Periodic Table is http://www.corrosionsource.com/handbook/periodic/periodic_table.gif What a Periodic Table is (cont.) What is a periodic table used for? Used to find Elements Protons Electrons What a periodic table is (cont.) Neutrons Electro negativity Atomic number Atomic mass Ect. Special name for each group what are the special names for each group? Group 1: alkali metals Group 2: alkaline earth metals Group 3-12: transition metals Group 17: halogens Group 18: noble gases Special name for each group (cont.) http://www.chemeddl.org/collections/tsts/PeriodicTable.gif Physical properties of metals What are the physical properties of metals? Efficient conduction of heat and electricity Malleability Ductility Lustrous appearance Physical properties of metals (cont.) http://3.bp.blogspot.com/_fwjNwZnc9JM/ShGo9HT_wFI/AAAAAAAAB GU/GVm8x1XECVQ/s400/metal_nonmetal_physical_diff.JPG metals, nonmetals, and metalloids Difference between metals, nonmetals, and metalloids Metal=solid Nonmetals=liquid/gas Metalloid=metal+nonmetal metals, nonmetals, and metalloids (cont.) http://media-2.web.britannica.com/eb-media/39/7339-004-23335A52.gif Ions Difference between cations and anions Cations are positive Anions are negative Ions (cont.) http://www.uwgb.edu/dutchs/Graphics-Geol/rockmin/ions.gif Quiz How is the periodic table organized? Is naming each group helpful? Explain. Are metals ductile? Explain your reasoning. What are the properties for metals, nonmetals, and metalloids? What is the difference between ions and isotopes? The periodic table is organized according to the atomic number. Naming each group helps because it is like a shortcut to finding an element. Yes because that is one of the properties in order to be a metal. The properties for a metal is solid, nonmetal is liquid or gas, metalloids are nonmetals plus a metal. Ions consist of electrons and isotopes consists of neutrons.
