Question
Predict the empirical formulas of the ionic compounds formed from the following pairs of elements. Name each compound.a. Al and Clb. Na and Oc. Sr and Fd. Ca and Se
Step 1
This can be done by looking at the periodic table. The group number (column) of an element can give us a clue about the charge of the ion it forms. For example, elements in group 1 form +1 ions, elements in group 2 form +2 ions, and so on. Similarly, elements in Show more…
