Peter performed an experiment to test which of the three compounds his teacher gave him was an ionic compound. The table shows his results. An 8-column table with three rows. The first row labeled compound has entries A, B, C. The second column labeled hard has entries no, yes, yes. The third column labeled brittle has entries no, yes, yes. The fourth column labeled forms crystals has entries no, yes, yes. The fifth column labeled dissolves in water has entries no, yes, yes. The sixth column has entries labeled boiling point (degrees C) with entries 2567, 1465, and not observed. The seventh column labeled melting point (degrees C) has entries 1083, 801, 180. The eight column labeled conducts electricity has entries labeled no, yes, no. Which compound (A, B, or C) is most likely an ionic compound?
