PPT-Ionic Compounds and Naming

Chapter 410411 and 5 Combining Elements When we begin combining elements we make compounds Two types Nonmetal and metal Nonmetal and nonmetal Each type has unique physical and chemical properties. Day 2. Working backwards: name to formula. It’s. . possible. . to. . determine. . a. . formula. . from. . a. . name. E.g. What is the formula of sodium oxide?. To get the answer, first write the valences:. Ch. . 16. Covalent Compounds. Covalent bonds. form when atoms share . their valence electrons. .. Covalent compounds. are formed from 2 or more nonmetals.. Rules for Naming Covalent Compounds. 1. Prefixes are used to show how many atoms of each element are present in the compound . Aqueous solutions of Sodium Hydroxide and Copper (II) Chloride combine to form an aqueous solution of . sodium. . chloride and . solid blue Copper Hydroxide . Write a skeleton equation. Balance the equation.. Putting electrical energy in to force the . nonspontaneous. change. electrolysis. Opposite process to electrochemical (voltaic) cells. Electrical energy is put into the reaction. The . nonspontaneous. Including Naming. Note: We likely won’t make it to covalent nomenclature, this is the one students find FAR easier than ionic. Please refer to the videos and naming hand out for help with this, and as always office hours, discussions, and . Covalent bonding. Ionic bonding. Ionic Bonding. Bonding as you’ve never imagined it. http://www.youtube.com/watch?v=BCYrNU-7SfA. Objectives. To consider the features of ionic and covalent bonds, and the compounds they make. MACROSCOPIC SCALE. Elements combine to make compounds.. ATOMIC SCALE. Atoms combine to make molecules, or extended structures.. What we’ll cover…. Compound Formulas. Ions. Monatomic. Polyatomic. Ionic Compounds. Bonding . is the joining of two atoms in a stable. arrangement.. There are two different kinds of bonding:. Elements will . gain. , . lose. , or . share . electrons to reach the electron configuration of the noble gas closest to them in the periodic table.. Covalent Compounds. Formed between two non-metals. Valence electrons are shared between atoms. Binary Covalent Compounds. Contain just two different types of non-metal elements. Some Different Rules. Steps:. 1.) . Cation. is written before anion.. 2.) Charges must cancel. (ionic compounds are neutral). 3.) Atoms must be in smallest whole number ratio.. Write the formula units for the following ionic compounds: 1.) lithium chloride, 2.) strontium oxide, 3.) ammonium phosphate.. I. onic compounds form between a metal and a nonmetal.. The metal forms a . cation. (+ ion) and the nonmetal forms an anion (-ion).. The . cation. is always named first and is the element name.. The anion is always named second – the root of the element name with an –ide ending.. I. Percent Composition. Think about this:. How would you find the percent of boys in our class?. # of boys (part)____. x 100% . Total # of students (whole). I. Percent Composition. . Do Now: Identify ionic compounds. CO. 2. MgCl. 2. NH. 4. Cl. NaOH. NH. 3. CH. 4. CuSO. 4. HF. Magnesium’s outer shell is now empty. Fluorine’s outer shell is now full. Lewis Diagrams for Ionic Compounds. Early in the 19. th. century John Dalton developed atomic theory. His theory explained the best available experimental data at that time. His theory has been modified since then with the discovery of other data, but his work was the initial ground work that we will examine first..
