###### Problem Details

Add charges, single electron dots, and/or pairs of dots as appropriate to show the Lewis symbols for the most stable ion of each element. Treat n = 4 as the valence shell in all cases.

As, Se, Br, K, Ca, and Ga

To draw Lewis symbols for atoms and ions and to balance Lewis structures for ionic compounds.

The Lewis symbol for an atom or ion shows the valence electrons as dots around the symbol for the element. Consider the following examples:

Dots may be placed on the four sides of a symbol (top, bottom, left, and right) in any order, but the maximum number of dots per side is two. Notice that in the correct configuration the number of unpaired dots is maximized.

The Lewis symbol for an ionic compound shows the Lewis symbols for the component ions side by side, with coefficients to indicate the relative numbers of ions. The Lewis structure of Mg3N2 is

If you compare the Lewis symbols for neutral Mg and N to that of their ions, you'll notice that all the valence electrons from magnesium were transferred to nitrogen.
