Question

The elements in red in the periodic table can form cations having more than one charge. Write the formulas and names of the compounds that are formed between the red cations and the blue anions depicted in the periodic table.

Accepted Answer

Welcome back everyone. Some metals can form cat ions with more than one possible charge. Provide the name of the compounds formed between one zinc and chlorine and to chromium and oxygen. Let's begin by recalling that for cat ions, if the metal has multiple charges use a Roman numeral for its name and then recall that for an ions if a non metal is used, keep the base name and add the suffix ID. So let's begin with part one. We have zinc and chlorine Recall that zinc is located in our transition metal section. So Zinc is a metal and chlorine recall is a non metal based on its position in group seven a or halogen group on the periodic table. So beginning with zinc recall that in our transition metal D block on our periodic table, zinc is associated with forming the zinc two plus cat ion and it only forms this single cat ion charge. Now, we have chlorine in which we recall is in group seven A on the periodic table and recall that any atom in group seven A forms an ion with the minus one charge. So we have our chloride minus one an ion. This means that we would keep its base name as chlor chlorine. We want to remove the suffix and replace it with the ending I'd. So therefore, the name of compound form between zinc and chlorine would be zinc chloride. This would be our first answer For part one. Now, moving on to part two of our prompt, we need the name of the compounds form between chromium and oxygen. And before I continue, I'd like to also point out that notice that for our formula of zinc chloride, we would have ZN cl two. Once we have our charges across our plus two charge from zinc will now become a subscript next to chlorine as to. And this is because this is an ionic compound and involves the transfer of electrons. So again, going back to part two of this prompt, we begin with chromium which we recognize as a metal and then oxygen based on its position in group six A on the periodic table is a non metal. So beginning with our metal chromium, we would recall that we find chromium in our transition metal D block of our periodic table and recall that it can form multiple charges. It forms the chromium two plus catty on the chromium three plus catalon and the chromium six plus catalon. Now recall that oxygen being in group six A of our periodic table means that any atom in group six A will form A minus to an ion charge. So we have our 02 minus an eye on. So we would keep our base ox and then we would add ID as our suffix, meaning we would form oxide for oxygen as our an ion. So therefore, if we cross the charges, sorry, this should say cross, if we cross the charges of our ions for each Kati on of chromium and our single an ion of oxygen, we would first form cr oh when we cross chromium two plus with 02 minus this, we can recognize as chromium, Roman numeral one oxide and correction, it should be Roman numeral two. Since we recognize that this was our two plus catalon of chromium. So chromium to oxide next we have when we cross our chromium three plus Catalan with R 02 minus an ion, we form cr sub two oh sub three. And this would represent Chromium In Roman numerals three oxide as the compound. And lastly, when we cross our chromium six plus canton with our oxide to minus an ion, we have C R sub to O sub six, meaning we have our compounds, Chromium, Roman numeral six V I oxide. And these last three compounds would be our last three final answers to complete this example. So all of our final answers highlighted in yellow correspond to choice C as the correct choice. I hope this made sense. And let us know if you have any question
