This came from https://en.wikipedia.org/wiki/Talk:Ununennium. I was just scrolling down until I found this comment about Ununennium (Element 119)'s final name. According to Kit Chapman (author of Superheavy) on Twitter, RIKEN is considering naming that element Nishinium (after japanese physicist Yoshio Nishina) when discovered (it was originally one of the possible names for Nihoniun). Its element symbol is Ns, as stated by Senta Sakane. http://blog.livedoor.jp/tgs0001/archives/50869582.html
