What is unique about the elements that are highlighted inpink?BSiGe AsSb Te?
Slide 7 / 130Slide 8 / 130Metallic Character of the ElementsWhat the relationship between metallic character and effective nuclear charge?Are they directly or inversely related? Is it accurate to say "Element A is moremetallic than element B" even if element B is a non-metal?1 In the periodic table, the elements are arranged in.A alphabetical orderB order of increasing atomic numberMore metallicLess metallicNon-metallicC order of increasing metallic propertiesD order of increasing neutron contentE reverse alphabetical orderBSiF I don't know how to answer this.Ge AsSb Te?Most metallicSlide 9 / 1302 Elements exhibit similar physicaland chemical properties.A with similar chemical symbolsB with similar atomic massesC in the same period of the periodic tableD on opposite sides of the periodic tableE in the same group of the periodic tableSlide 10 / 1303 Which pair of elements would you expect toexhibit the greatest similarity in their physicaland chemical properties?A Li, NaB Cs, BaC Ca, SiD Ga, GeE C, OSlide 11 / 1304 Which one of the following is a nonmetal?A WSlide 12 / 1305 Potassium is a and chlorineis a .B SrA metal, nonmetalC OsB metal, metalD IrE SC metal, metalloidD metalloid, nonmetalE nonmetal, metal
Slide 13 / 130Slide 14 / 130Review: Octet RuleAtoms tend towards having complete outer shells ofelectrons (remember stability).Valence Electrons and theOctet RuleA full outer shell will have:2 electrons in the s subshell and6 electrons in the p subshell ( s p configuration)26Octet rule: atoms tend towards having a total of 8 electrons8 valence electrons make an octetWhich elements on the periodic table have a completeouter shell? What is true about these elements relativechemical reactivity?Return to Tableof ContentsSlide 15 / 130Slide 16 / 130Valence ElectronsValence ElectronsValence electrons are the electrons in thehighest occupied energy level of anelement’s atoms.1 2Number of valenceelectrons in neutral atoms:3 4Valenceelectron1-4The valence electrons determine thechemical properties of an element. Why doyou think this would be true?To find the number of valence electrons in an atom of arepresentative element (elements found in the s and p blocks),simply look at its group number.Atoms in group 3 have 3 valence electrons,atoms in group 17 have 7 valence electrons, etc.There is one exception:helium has only 2 valence electrons.Slide 17 / 1306 How many valence electrons does potassium have?A 3Slide 18 / 1307 How many valence electrons doesAluminum have?A5B7C 19C3D 4D27E 8E13B 1567 8

Some of these trends can be seen in the properties of atoms we covered in the last unit: atomic size, ionization energy, electronegativity and metallic character.
Periodic Table and Bonding I. Handout: Periodic Table and Bonding Notes II. Periodic Properties and the Development of the Periodic Table i. Mendeleev's First Periodic table I. The first periodic table was arranged by Dimitri Mendeleev in 1869. i. He was a professor of Chemistry. at the University of St. Petersburg in Russia and was
History of Periodic Table 1869: Dmitri Mendeleev organized the periodic table based on atomic weights “Father of the Periodic Table” 1913: Henry Moseley rearranged the periodic table based on the positive charges in the nucleus Lead to the periodic law: the states that a periodic pattern appears in
The Periodic Table Chapter summary 6:1 History od the Periodic table 1) Mendeleev’s Periodic table 2) Problems with early periodic tables 6:2 Modern Periodic table 1) Key points: Periodic law, Periods and Groups, 3 broad classes of elements
Unit 3.2: The Periodic Table and Periodic Trends Notes . The Organization of the Periodic Table. Dmitri Mendeleev was the first to organize the elements by their periodic properties. In 1871 he arranged the elements in vertical columns by their atomic mass and found he could get horizontal groups of 3
NGSS Lesson- Periodic Table Patterns Grade/ Grade Band: 9-12 Topic: Periodic Table Patterns Lesson # 1 in a series of 1 lessons Brief Lesson Description: Students will use cards, representing elements to build a build of the periodic table. Performance Expectation(s): HS-PS1-1.Use the periodic table as a model to predict the relative properties of elements based on the
1 Explain how the periodic table is an example of a model. 2 Explain how elements are arranged on the periodic table based on similarities. 3 Identify Groups and Periods on the Periodic Table. 4 Identify the 3 main classes of elements on the periodic table 5 List the properties of

3rd Grade – Persuasive Essay . Teachers may want to invest time in reading Kindergarten-Second Grade MAISA Writing Units of study or talk to previous grade level teachers before beginning this unit. If students have not had previous experience in a writing workshop or with aligned units of study, teachers may want to include lessons from previous grade levels as support and build towards .
