Naming Compounds Binary compounds compounds that are composed of two elements We will examine two classes of binary compounds 1.Naming Compounds Common names were originally developed to name compounds Ex: Epsom salts, milk of magnesia, gypsum and laughing gas Too many common names.a system had to be developed!.Regents Chemistry Chemical Nomenclature.= worksheet Dissolving Ionic CompoundsVideo Does this work? Ionic Compounds Combination of cation and anion Write cation first and anion second When combining, we must consider electrical charge Ions combine in such a way to make a zero net charge Total charge of cations + Total charge of anion = Zero net charge.Writing out ionic charges Sodium ion Magnesium ion Gain e - Lose e.Ionic charges from Periodic Table See pg.***Keep parent name and add word - ion***.**Change ending of parent name to -ide and add word - ion**.Regents Chemistry Ions and Oxidation States.Regents Chemistry Information on the Table Average Atomic Mass Atomic Number Isotopes.Elements can have different forms Solid metals differ from solid non-metals In fact, different forms of the same element can occur These are called allotropes Ex: Carbon Diamond (very hard) Graphite (soft) Buckministerfullerene (newly discovered) End.Natural Physical States Metals are solids at 25 C Noble gases are gas at room 25 C and are individual atoms Several others are gases and diatomic at 25 C (H 2, N 2, O 2, F 2, Cl 2 ) Only two elements are liquids at 25 C Bromine and Mercury.Examples Argon (noble gas) Nitrogen and oxygen.After we use a chemical process to separate the elements in a compound, we find the elements to be: Monoatomic atoms only (1) atom of the element Diatomic molecules (2) atoms bonded together Natural States of Elements Most of the matter around us consists of mixtures Mixtures contain compounds Atoms of individual elements are not often found in nature in pure form Some exceptions: gold, platinum and silver Also noble gases do not combine readily Ex Helium gas in underground deposits.Ductility (they can be pulled into wires) 4. Physical Properties of Metals 1.Efficient conduction of heat and electricity 2.Malleability (they can be hammered into thin sheets 3.Divisions of the Periodic Table Metals Alkali metals Alkaline earth metals Transition Metals Metalloids Nonmetals Halogens Nobel gases.The Periodic Table The periodic table is arranged according to Atomic Number The first table, by Russian chemist Dmitri Mendeleev, was arranged by atomic mass, but this was not accurate Current arrangement shows many important trends.Recap Nucleus electrons The nucleus contains protons and neutrons Electrons surround the nucleus in a cloud Atomic number is the number of protons Atomic mass is the sum of protons and neutrons.Regents Chemistry Introduction to the Table Groups and Families Elements of Metals, Nonmetals and Metalloids.Regents Chemistry Topic 2 The Periodic Table and Formulas / Equations.

All labs must be completed in a timely manner to receive the full 15 points. After five or more absences or ten or more lateness, forty percent of your classwork grade will be reduced. If you are consecutively late without a pass you risk the possibility of failing the class. If absent a note must be given to me the next day If absent visit class page to see what you have missed Quizzes or Exit Slips (announced on class page) (10%) Notebooks may be checked at any time during marking period
Y ou must participate in class or group activities If numerous homework assignments are missing you may risk failing for the marking period Homework can be handed in 1 day after date assigned. Casey’s Class Page ( ) or from the homework (HW) board posted in the classroom. If you are absent, you are responsible to retrieve homework from Ms. Answers must ALWAYS show work or calculations If absent on an exam day you must bring a note and makeup the exam within the week Unit VIII: Mathematics of Formulas and Equations The major units we will be studying are as follows: This year we will be exploring chemistry topics to help prepare you for the Regents Exam in June.
