Four New Elements
By Alisa Carlson
Basic information about the four new elements
The job of the IUPAC is to advance the world to help us understand more about our world. This Union was offical in 1919 and was created to make more standards for how to name elements and establish offical number for things such as atomic mass.
How to write electron configurations - Kernel Method
Example: [He] 2s2 2p2
This is the electron configuration for carbon.
This element has an atomic number of 6. There for the noble gas with an atomic number less then it would be Helium and is in the second period. there for in the brackets there would be the atomic symbol of He. Also the electron would continue from 2s.
For longer ones it works the same way just using different noble gases and elements.
