Goodbye Brazilium and Mexicium, Hello Newtonium and Nebulium! Both names originated from proposed elements that didn't actually make it into the Periodic Table. As for extension, I made my own predictions for Unbiunium through Unbioctium, and I have an explanation about them. The idea for Nalakium came from @Kuutti85, who created a character called Nalabudgie. This inspired me to add it in. It's basically similar to Astatine, but it isn't a halogen. Victorium through Berzelium also came from misidentified names. I even repurposed "Bz" for Berzelium. Rozdymium and Paliodymium came from the Greek words for "pink twin" and "old twin", similar to Praseodymium (green twin) and Neodymium (new twin). "Rz" for Rozdymium also came from Fandomium. Christium (the last one on this list) was named after Jesus Christ. No reason needed.
Credit to @Kuutti85 for Nalakium and to all. And what will happen to Brazilium you ask? I'm planning to change it's number to 172 for unknown reasons.
