I just got the tab 3 today. I noticed it is slow to charge and will not charge while I'm using it. Is this normal??

Welcome to AC.☺

Are you using the mains charger, or charging from a PC via USB lead? If the latter, charging will be slower and may not allow you to use the device at the same time.

I'm using the charger that came with it, plugged into the wall.

So far as I know it ought to be able to charge while you're using it. Please stand by while I consult certain experts on that device.

Does it work better with any other charger? If not, I would call Samsung, and let them know.

Is it a Samsung branded charger. Did it come from a reputable seller?
Try to see what the output is of the charger. 500-700ma/0.5-0.7A is a bit low.
Does it have a separate cable?

The amount of charge the battery gets is the amount the device can draw from the charger (that's fixed inside the device, no matter how much more current the charger is capable of supplying) minus the amount of current being used by the device. If you're playing a heavy game, or are on a web page with a lot of Javascript, the tab is going to be using a lot of current, and there won't be much left to charge the battery.

That's not just normal, it's electricity 101 - Kirchoff's Law (all the current entering a junction is equal to all the current leaving the junction) on a larger scale.
If the tablet can draw 1,200mA, and is using 1,000mA, the battery is getting only 200mA charge, a far cry from the 1,200mA it would get if the tablet were off. (And it will take 6 times as long to charge.)
