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: CaCl 2 )

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 _______________ 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 (SO 4 ) 2-, phosphate (PO 4 ) 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
