PPT-Flashcards: Naming Molecular Compounds

By Mr Gates Examples provided in part by Ms Allee Provide the Formula phosphorus dichloride Answer PCl 2 Provide the Formula s ilicon dioxide Answer SiO 2 Provide the Name Cl 2 O. 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:. Covalent Compounds. Warmup. – write out the answer. Identify these compounds as covalent or ionic. SiO. 2 . is _____. FeS. 2 . is _____. cobalt(III) chlorate is _______. H. 2. O is _______. An ionic bond is____. IUPAC. BOHR DIAGRAMS FOR ATOMS. TYPES OF CHEMICAL BONDS. MOLECULAR COMPOUNDS. TYPES. SIMPLE COVALENT. COMMON NAME. IONIC COMPOUNDS. SIMPLE IONIC. MULTIVALENT. POLYATOMIC/COMPLEX. HYDRATED IONIC. ACIDS. 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 . Chapter 4.10,4.11 and 5. Combining Elements. When we begin combining elements we make compounds.. Two types. Non-metal and metal. Non-metal and non-metal. Each type has unique physical and chemical properties. CHEMICAL NOMENCLATURE. Writing Formulas. Binary ionic compounds. Ternary ionic compounds. Binary molecular compounds. Acids. Ionic Compounds. Composed of oppositely charged ions. Positive ion is a . cation. Ionic Bonding and Writing Formulas. Common Anion Name Changes. Nitr. ogen .  . Phosph. orus .  . Ox. ygen .  . Sulf. ur .  . Selen. ium .  . Fluor. ine .  . Chlor. ine .  . Brom. 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. 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. 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. . 3-. 2. Questions for Consideration. How do ionic compounds differ from molecular compounds?. What kinds of ions are in ionic compounds?. What do formulas for ionic compounds represent?. How are ionic compounds named?. Packet #1 (blue). (Buckle up, kiddoes!). Organic Chemistry. = The study of carbon-containing compounds. More specifically: those compounds that have a . carbon backbone. There are well over 1 million known organic compounds!. Sharing Electrons. The names of molecular compounds need prefixes because several different compounds can be formed from the same two nonmetals. .. Learning Goal . Given the formula of a molecular compound, write its correct name; given the name of a molecular compound, write its formula..
