#4 is radiometric dating
#5 isotopes of an elelment
#7 radiation therapy
Hello too to you, Amy.
1. I'll share with you some sites with images, etc. Then you can enter whatever you are looking for, but be sure you spell fusion correctly!
4. Radiometric dating is one term
5. Here's an answer from Yahoo, 4 months ago: Isotopes. When it has a different number of electrons, they're called ions.
Example: Carbon 12 and Carbon 14 (Used in carbon dating) Carbon 12 has 6 protons and 6 neutrons, while Carbon 14 has 6 protons and 8 neutrons.
6. a nuclear reaction?
This is not my area so be sure to check with your textbook!
