The correct atomic symbols of carbon, calcium, copper and cobalt respectively area) C, Cu, Ca, Co b) C, Ca, Co, Cu c) C, Ca, Cu, Co d) Ca, C, Cu, Co

Identify which of these might be symbols for elements.PtPTfFI'm not sure

Under Ionic or Covalent write in a "i" for ionic and a "c" for covalent.  The next two blanks under name write the name of the compound. For the name of the compound. If the metal requires a Roman numeral, then make sure you put the name of the cation(metal) and the Roman numerals without a space in between them and use parenthesis around the roman numeral, like this:   iron(II) or copper(I) Formula PbSO4ionic or covalent Name
