Writing Formulas For Ionic Compounds Leave out all subscripts that are 1 PbO2 PbO 2 Exercise 5 5 2 5 5 2 Write the chemical formula for an ionic compound composed of each pair of ions the calcium ion and the oxygen ion the 2 copper ion and the sulfur ion the 1 copper ion and the sulfur ion Answer a CaO
Writing ionic formulas requires knowing the charges of ions in the compound In general the charge of the positive ion is written on the negative ion and the charge of the negative ion is written on the positive ion creating a cross over For example if the Calcium ion is 2 and Chloride ion is 1 then Calcium Chloride is written CaCl2 AboutTranscript To find the formula of an ionic compound first identify the cation and write down its symbol and charge Then identify the anion and write down its symbol and charge Finally combine the two ions to form an electrically neutral compound In this video we ll walk through this process for the ionic compound calcium bromide

Because the ionic compound must be electrically neutral it must have the same number of positive and negative charges Two aluminum ions each with a charge of 3 would give us six positive charges and three oxide ions each with a charge of 2 would give us six negative charges The formula would be Al 2 O 3 Answers The formulas featured in the Formulas for ionic compounds sheet are Sodium carbonate Na 2 CO 3 Silver nitrate AgNO 3 Calcium bromide CaBr 2 Copper hydroxide Cu OH 2 Iron II nitrate Fe NO 3 2 Iron III iodide FeI3 Lead sulfate PbSO 4

To name main group anions we add the suffix ide to the end of the element s name Cations and anions combine to form ionic compounds Ionic compounds are named with the cation first and the anion last The same convention is used when writing their chemical formulas Ionic compounds must be electrically neutral This chemistry video tutorial explains how to write chemical formulas of ionic compounds including those with transition metals and polyatomic ions Chemistry
To write the name of an ionic compound based on its name we first need to remember the valency and the names of the common ions Let s start with the alkali and alkaline earth metals These are on the left side of the periodic table groups 1 and 2 and tend to form cations with charges according to their group number AboutTranscript Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions For binary ionic compounds ionic compounds that contain only two types of elements the compounds are named by writing the name of the cation first followed by the name of the anion
