It is produced by the electrical decomposition of sulfur hexafluoride (SF6)an essentially inert insulator used in high voltage systems such as transmission lines, substations and switchgear. We call this feature the ionic or covalent calculator. There is a simple and easy way to identify ionic versus compounds. The two main types of chemical bonds are ionic and covalent bonds. All the remaining transition metals form multiple charged ions (iron for example, forms Fe+2 and Fe+3 and thus has multiple charge states). So Sn+4 can easily polarise Cl- ion which make Sn-Cl bond covalent. It belongs to the 1st period and 6th group, alkali metal of the periodic table. Just use a periodic table which includes it and read it for the selected element. Transcribed image text: Classify the compound SO_2 as ionic or covalent. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. For example, the electronegativity value of hydrogen is 2.20, and fluorine is 3.98. The "x" must be +3. Remember to first determine whether the compound is ionic or molecular!
