1 Atoms, Molecules, Elements, Compounds, Mixtures and LOCOM S8P1. Obtain, evaluate, and communicate information about the structure and properties of matter. E. Develop models by analyzing patterns within the periodic table that illustrate the structure, composition, and characteristics atoms and simple molecules. Term Info Picture Mendeleev The father of the periodic table. Periodic Table The periodic table is an arrangement of the chemical elements, ordered by their atomic number (number of protons), electron configurations, and recurring chemical properties. Period (series) Horizontal rows on the periodic table. Group (family) Vertical columns on the periodic table. Members of the same group have similar properties and the same number of valence electrons. Periodic Law the law that states that the repeating chemical and physical properties of elements change periodically with the atomic numbers of the elements Periodic Appearing or occurring at intervals
2 Atomic Number The number that tells you the number of protons OR the number of electrons Atomic Mass Electrons The massive number-the number that represents the number of protons AND neutrons together Negatively charged particles in an atom (smallest) Protons Positively charged particles in the nucleus of an atom. Neutrons Particles in the nucleus of the atom that do not carry a charge. Valence Electron An electron on the outermost level of the electron cloud. Metal a material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity (e.g., iron, gold, silver, copper, and aluminum, and alloys such as brass and steel). Nonmetal Nonmetals have properties opposite those of the metals. The nonmetals are brittle, not malleable or ductile, poor conductors of both heat and electricity, and tend to gain electrons in chemical reactions.
3 Metalloid The zigzag stairs that separate metals and nonmetals; metalloids have characteristics of both metals and nonmetals. Brittle Crumbles easily. Shiny Reflects light well; metallic. Conductive Allows heat and electricity to pass through it easily. Metals are good conductors. Dull Not shiny Transition Metals Metals in groups Malleable Can be hammered into thin sheets. Ductile Ability of a material to be stretched into a thin wire without breaking.
4 Noble Gas The last column of the periodic table. The noble gases are nonreactive because they have a full outer electron shell. Learning Targets: 1. I can develop models by analyzing patterns within the periodic table. 2. I can calculate the atomic number and atomic mass in relation to the subatomic particles. 2. I can explain how elements are arranged in the periodic table. 3. I can compare and contrast metals, nonmetals and metalloids based on their properties and their location in the periodic table. 4. I can describe the difference between a period and a group. 5. I can navigate and interpret the Periodic Table effectively to find information about an element. 6. I can analyze the periodic table in order to determine different atomic properties.
