WebAboutTranscript. 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. Web1 day ago · Step 1: Count the total number of valence electrons present in the molecule/ion. For sulfate ions, we have one molecule of sulfur and four molecules of oxygen. Sulfur and oxygen both belong to the same group in the periodic table ( the chalcogen family) and have six valence electrons each. total valence electrons in SO42- = 6*1 + 6*4 +2 = 32.
