1.      Superheavy elements can only be discovered through synthesizing them in a laboratory.

 

 

2.      Calcium-48 was used to form elements 113-118 because it is stable and neutron rich.

 

 

3.      When nuclei in the beam combine with target nuclei, protons carry energy away.

 

 

4.      The number of neutrons is unimportant in trying to form a heavy nucleus.

 

 

5.      Californium-249 can only be produced in a laboratory through a series of neutron captures, followed by beta decay.

 

 

6.      Californium-249 has a half-life of more than 350 years.

 

 

7.      Projectile nuclei ions are accelerated in a cyclotron until they have the right energy to be sent toward the target nuclei.

 

 

8.      Approximately 10% of the projectiles produced in the cyclotron produce the desired product.

 

 

9.      The detector calculates the mass of an ion by measuring the time required for an ion of interest to travel between two grids and the distance between the grids.

 

 

10.  As of the writing of this article, all of the elements through element 118 have been discovered or created in a laboratory.
