Deduce the empirical formulae and draw the Lewis structures for the ionic compounds formed by the following pairs of elements. Na, O, K, S, Na, P, Mg, Br, AI, F,
Ca, O, Li, S

Explanation

To deduce the empirical formulae and draw the Lewis structures for the ionic compounds formed by the given pairs of elements, we will follow these steps for each pair:

### Step 1: Identify the Cation and Anion
For each pair of elements, determine which element will form a cation (positively charged ion) and which will form an anion (negatively charged ion).

### Step 2: Determine the Charges of the Ions
Identify the charge of the cation and anion based on their positions in the periodic table.
