Thus For S,I units of force:

The right answer for the question that is being asked and shown above is that: "C. <span>. The properties change going across each row. " the </span>statement that applies to the horizontal rows or periods in the periodic table is that t<span>he properties change going across each row. </span>
These balloons will be attracted, as you have shown in the picture, there are two positives, they are not in the same spot. when two of the same poles are put together, they rebel each other, since the two positive poles are not in the same area of the balloon, the balloons will attract each other. I hope this helps :)
