400
When naming ionic compounds which is written first?
The positive
400
How many protons does Sn (Tin) have?

Can you add Radon and Francium together why or why not?
No because Radon is a Noble Gas and its Valence electron shell is already full adding one more to the shell would put it over the magic number of 8.
