Name: _____________________________________ Class: ______ 6.3 Naming Compounds and Writing Formulas Chapter 6 Chemical Bonds
What are we going to learn? • How to write the name and formula of ionic and covalently bonded compounds
Naming Ionic Compounds • Ionic compound ____________: distinguishes the _______________ from _________ ionic compounds containing the ______________________________ • ________________________ (ex: calcium chloride) • Ionic compound ________________: describes the ________ of the ________ in the _______________ • _____________________________________(ex: CaCl2)
Binary Compounds • If a ___________________ is made from only ________________________ is a ______________compound (Ex: salt is a binary compound made of sodium and chlorine - sodium chloride) What’s in a Name? • To ________ a binary compound: list the name of the ____________ (+ ion) ___________________ the name of the ______________ (- ion)
Cations – First in Naming • ____________: simply the name of the ___________ (no changes) • Ex: sodium atom and sodium ion • This _______________ groups ____, _____ and ________________ • Group _____ has a _______________ • Group _____ has a _______________ • Aluminum (Group _____) has a _____________
_______________________ with _____________________ possible ________ have a different naming strategy • _________ of the ion contains a _________________ to indicate the ___________ • Ex: copper (II) ion
Anions – The Followers • _________: use name of the ______________ with the _______________replacing –ine (ex: chlorine atom and chloride ion) • _______________ are on the _________________ of the periodic _________ • Ex: sodium chloride (cation) (anion)
Formulas • If you know the __________ of an ionic compound, you can ________ its _________________________ • Chemical formula includes _____________________ of the elements and ____________ (indicating _______________________) How do you write a formula? • Write the symbol of the __________ first • Follow with the symbol of the __________ • Use _______________ to show the ________ of the ions in the compound
Polyatomic Ions • A ____________________________________ that has a _____________________________ charge and ___________________ • Ex: nitrate (NO)3-, sulfate (SO4)2-, phosphate (PO4)3-
Molecular Compounds • _________ and _____________ of a molecular compound describe the _______ and _________________________ in a ____________ of the compound • These _____________ are usually on the _________________ of the periodic table • _____________ in the compound _____________________________
Naming a Molecular Compound • ____________________ element name appears _________ (most ________ in the periodic table) • Name of the ________________________ is changed to end in the suffix -_______ • Ex: carbon dioxide • ____________ indicate ____________ of atoms in the ______________ • Ex: ___ shows that there are _______ carbon __________ in the molecule
Molecular Formula • _________ the ______________ for the elements in the _________ the elements ___________ in the ________ • ______________ in the compound name _____________ the _____________________ of ____________________ in the molecule • ____________ appear as _________________ in the ____________
Writing Chemical Formulas for Binary Compounds Practice • 1 - Write the symbols for the elements.2 - Look up element ion charges and write them as superscripts to the right of the elemental symbols.3 - Use the correct combination of ions to produce a compound with a net charge of zero. Multiple ions are indicated with subscripts. • lithium oxide • potassium chloride • calcium oxide • barium bromide
Writing Chemical Formulas for Binary Compounds with Polyatomic Ions • lithium carbonate • calcium nitrate • ammonium sulfide • sodium sulfate Writing Chemical Formulas for Transition Metals Practice • Lead (IV) carbonate • Copper (II) nitrate • Iron (III) oxide • Tin (IV) fluoride
Writing Chemical Names for Transition Metals Practice • Fe(NO3)2 • CuF2 • NiS • FeCl2 Writing Chemical Formulas Practice • zinc carbonate • barium oxide • cadmium fluoride • magnesium sulfide • lithium phosphate
Writing Chemical Names Practice • FeF2 • FeF3 • Hg2Br2 • HgBr2 Writing Chemical Names Practice • BaSO4 • FeF2 • CuCO3 • CaS • MgO • KCl
NO • N2O • NO2 • N2O5 • N2O3
