Chapter 19:Above(and Beyond) the Periodic Table

1. Francium is terribly dangerous. Why don't we hear about it being used as a weapon?

It is so hard to find. The second most rarest element on earth.

2. What are the other two fundamental forces besides strong and electromagnetic forces? Which is responsible for radiation?
Strong nuclear force and the electrostatic force. Nuclear force is responsible for radiation. 

3. What is the "island of stability?"
The reason that somehow heavy isotopes will help extend the periodic table.

4. Why is it believed that we could never go beyond element 137 on the table?

The reason why we could never go beyond 137 on the periodic table is because with 137 protons, it would be going faster than the speed of light, which can obviously never happen.

5. Find alternative ways to arrange the periodic table online and comment on them? Would you prefer the table was designed differently? Why or why not?
I love the periodic table the way it is.  #don'tchange
