Flerovium Konfigurasi elektron

Flerovium (sebelumnya bernama Ununquadium) adalah unsur kimia buatan dalam sistem periodik unsur yang memiliki lambang Fl (sebelumnya Uuq) dan nomor atom 114. Flevorium diduga memiliki sifat-sifat gas mulia ketimbang sifat-sifat logam. Pada tanggal 29 Mei 2012 nama Flerovium telah disetujui oleh IUPAC setelah sebelumnya menggunakan nama Ununquadium. Nama diambil dari Flerov Laboratory of Nuclear Reactions di Dubna, Rusia, tempat di mana unsur ini dibuat.[16]
