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.
To add formal charges, click the button below (which will turn yellow when activated) before clicking on the molecule. You may need to hit Enter on your keyboard after typing the charge to make it register before clicking submit.
Place charges and electron dots as needed on each ion. To add a charge, click the +/- button, then click on an atom and type the desired charge.
As, Se, Br, K, Ca, Ga
