    17. 17. Confused about Charge?•Atoms are like batteries they havezero total charge.•Think about charges on an atomlike charges on a battery!On one end there is a positive (+)charge on the other a negative (-)charge, but the whole battery has www.diytrade.com/china/4/products/2196408/Pan...zero charge because they balanceout.
    18. 18. A Closer Look at the Nucleus•2 particles http://www.fotosearch.com/photos-images/atom.html
