ion sheet Ex NaOH 9 Na OH39 9 sodium hydroxide Use Roman numerals to indicate oxidation number of cation if there is more than one kind This will be indicated on your ion sheet Ex PbSO4 9 Pb2 304392 9 lead 11 sulfate Pb2 9 lead 11 Pbquot4 gt lead IV Molecular Compounds nonmetal nonmetal have a covalent bond use pre xes except when there is only one of the rst element Ex CO 9 carbon monoxide First element get the name from the periodic table Second element root of element name and ending ide All names of molecular compounds that you will have will end in ide Use anion name from sheet with pre xes Ex N203 9 dinitrogen trioxide 1 mono 6 hexa 2 di 39739 hepta 33 tri 8 octa 4 tetra 39 9 nona 5 penta 10 deca Hydrates ionic compounds with water molecules locked up in the lattice structure Name rst part according to ionic rules Use pre x to indicate the number of water molecules attached Add the word hydrate Ex CuSO439 5 H20 9 copper II sulfate pentahydrate Acids all acids that you will have will start with an H If it starts with an H us 9935 seawe acid rules to name compound except water 39 Binary acid two element acid hydrogen monatomic anion pre x hydro Ex HCl 9 hydrochloric acid root of anion suf x ic add the word acid t r Ternary or Oxyacid three or more elements and one of them is oxygen hydrogen a polyatomic anion with oxygen Name according to the anion If the anion ends in ate 9 ic ex HNO3 9 H N0339 9 nitrate 9 nitric acid ite 9 ous HNOZ 9 H N0239 9 nitrite 9 nitrous acid Add the word acid I A GUIDE TO NAMING COMPOUNDS AND WRITING CHEMICAL FORMULAS Rules for wriTing formulas of ionic compounds 1 WriTe The symbol for The posiTively charged ion firsT This will almosT always be a meTai 2 Use The cross and drop rule ouTlined below To deTermine The subscripT a WriTe The correcT charge above each ion b Circle The number represenTing The charge of each ion and Then cross and drop To give subscrist The charge of The firsT aTom becomes The subscripT for The second aTom and vice versa c Reduce The formula To The simplesT form by dividing The subscrist by any common muITiple Examples calcium chloride 9 Caz Cl 9 CaClz magnesium oxide 9 Mg 02 9 MgzOz 9 M90 Rules for naming ionic compounds V 1 Name The firsT elemenT by iTs elemenTal namequot 2 If The firsT elemenT is a meTal ThaT can have more Than one charge idenTify iTs charge by using Roman numerals in parenTheses 39 2 Add The correcT name of The anion monaTomic anions will end in ide polyaTomic ions will usually end in iTe or aTe Examples NaF is sodium fluoride CuClz is copperII chloride KN03 is poTassium niTraTe Rules for wriTing formulanaming of binary molecular compounds 1 Prefixes are used To represenT The number 39of aToms presenT 2 WriTe The name of The elemenT ThaT is farTh39esT lefT in The periodic Table firsT or farThesT down if They are in The same group 3 If There is only one of These aToms presenT no prefix is needed oTherwise use TheappropriaTe prefix 4 The name of The second elemenT should begin wiTh a prefix and The ending of The elemenT39s name should be changed To ide 5 A vowel aT end of a prefix is ofTen dropped if The elemenT39s name begins wiTh a vowel Examples 652 is carbon disulfide N204 is diniTrogen TeTroxide P453 is TeTraphosphorous Trisulfide Rules for wriTing names of acids v Acids are compounds of The general form HnX where X represenTs eiTher 39a lone elemenT or a polyaTomic ion 1 When The name of X ends in ide Then The acid name begins wiTh hydro and The anion39s suffix ide changes To ic and is followed by The word acid 2 When The name of X ends in iTe Then The acid name is The sTem of The anion and The suffix changes from iTe To ous and is followed by The word acid 3 When The name of X ends in aTe Then The acid name is The sTem of The anion and The suffix changes from aTe To ic and is followed by The word acid Examples HCI is hydrochloric acid H25 is hydrosulfuric acid HNthi slniTrousfacjd is sulfurous acid HN03 is39nifric39a39cidfl lgsa is sulfuric acid Rules for wriTing names of bases MosT bases are ionic compounds ThaT conTain hydroxide OH39 or carbonaTe CO3Z39 1 Name These bases as you would any oTher ionic compound The name of The caTion is followed by The name of The anion Examples NaOH is sodium hydroxide 39 Coco is calcium carbonaTe Gaui Lusscecg Law OmoQ T direclk1 FroPor konaD A TIEquot 2
