• How to write the name and formula How to write the name and formula of ionic and covalently bonded of ionic and covalently bonded compoundscompounds

Naming Ionic Naming Ionic CompoundsCompounds
• Ionic compound Ionic compound namename: distinguishes : distinguishes the the compoundcompound from from otherother ionic ionic compounds containing the compounds containing the same same elementselements
• Name =Name = wordswords (ex: calcium (ex: calcium chloride)chloride)
![Page 4: 6.3 Naming Compounds and Writing Formulas](https://reader036.vdocument.in/reader036/viewer/2022081505/56815a2d550346895dc76f1e/html5/thumbnails/4.jpg)
• Ionic compound Ionic compound formulaformula: describes : describes the the ratioratio of the of the ionsions in the in the compoundcompound
• Formula = Formula = numbers of elementsnumbers of elements (ex: CaCl(ex: CaCl22))

Binary CompoundsBinary Compounds• If a If a compoundcompound is made from only is made from only
twotwo elements elements is a is a binarybinary compound compound (Ex: salt is a binary compound made (Ex: salt is a binary compound made
of sodium and chlorine - sodium of sodium and chlorine - sodium chloride)chloride)

What’s in a Name?What’s in a Name?• To To namename a binary compound: list the a binary compound: list the
name of the name of the cationcation ( (++ ion) ion) followed followed byby the name of the the name of the anionanion ( (- - ion) ion)

Cations – First in NamingCations – First in Naming• CationCation: simply the name of the : simply the name of the metalmetal
(no changes) (no changes) • Ex: sodium atom and sodium ionEx: sodium atom and sodium ion

• Transition metalsTransition metals with with more than more than oneone possible possible chargecharge have a different have a different naming strategynaming strategy
• NameName of the ion contains a of the ion contains a RomanRoman numeralnumeral to indicate the to indicate the chargecharge
• Ex: copper (II) ionEx: copper (II) ion

Anions – The FollowersAnions – The Followers• AnionAnion: use name of the : use name of the nonmetalnonmetal
with the with the suffix suffix ––ideide replacingreplacing –ine –ine (ex: chlorine atom and chloride ion(ex: chlorine atom and chloride ion))• NonmetalsNonmetals are on the are on the right sideright side of of
the periodic the periodic tabletable• Ex: sodium chlorideEx: sodium chloride (cation) (anion)(cation) (anion)

FormulasFormulas• If you know the If you know the namename of an ionic of an ionic
compound, you can compound, you can writewrite its its chemical formula chemical formula
• Chemical formula includes Chemical formula includes chemical chemical symbolssymbols of the elements and of the elements and numbersnumbers (indicating (indicating amounts of amounts of each element)each element)

How do you write a How do you write a formula?formula?
• Write the symbol of the Write the symbol of the cationcation first first • Follow with the symbol of the Follow with the symbol of the anionanion • Use Use subscriptssubscripts to show the to show the ratioratio of of
the ions in the compoundthe ions in the compound
