Question
Which ionic compound is expected to form from combining the following pairs of elements? (a) barium and fluorine, (b) cesium and chlorine, (c) lithium and nitrogen, (d) aluminum and oxygen.
Step 1
The ionic charge is determined by the number of electrons an atom loses or gains to achieve a full outer shell. For example, barium (Ba) is in group 2 of the periodic table, so it loses 2 electrons to achieve a full outer shell, giving it a charge of +2. Fluorine Show more…
