Europa2433 this isnt for a test, quiz, or homework, its for self guided notes that the teacher wont even look at, so please stop deleting it. i'm just looking for some help

1. Considering the structure of the atom (our 2nd unit of Chemistry) what location of the
atom do you think nuclear chemistry deals with?
2. Look at the periodic table image in the notes (also use your own periodic table that
shows more information). What can you say about the size of the majority atoms
described as radioactive (colored purple on the periodic table image)?
3. What 2 features of nuclei make them likely to be radioactive?
