About flerovium

Flerovium is a chemical element with the symbol Fl and atomic number 114. It is a post-transition metal in group 14, period 7, p-block. Flerovium was first discovered in 1998. It is named after the Flerov Laboratory in Dubna. Its bulk properties have never been measured because only a few atoms have been made; it is expected to be a solid at room temperature.

Flerovium electron configuration

The electron configuration of flerovium is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁶ 6s² 4f¹⁴ 5d¹⁰ 6p⁶ 7s² 5f¹⁴ 6d¹⁰ 7p², or in short [Rn] 7s² 5f¹⁴ 6d¹⁰ 7p². Its electrons occupy 7 shells: K = 2, L = 8, M = 18, N = 32, O = 32, P = 18, Q = 4. Flerovium has 4 valence electrons in the Q shell (7s² 7p²), which is why it sits in group 14. For this superheavy element the configuration is a theoretical prediction.

Filling order: 1s²(2) → 2s²(4) → 2p⁶(10) → 3s²(12) → 3p⁶(18) → 4s²(20) → 3d¹⁰(30) → 4p⁶(36) → 5s²(38) → 4d¹⁰(48) → 5p⁶(54) → 6s²(56) → 4f¹⁴(70) → 5d¹⁰(80) → 6p⁶(86) → 7s²(88) → 5f¹⁴(102) → 6d¹⁰(112) → 7p²(114)

Uses of flerovium

Flerovium has no practical use outside research, because it can only be made a few atoms at a time in particle accelerators.

Safety

Only a handful of flerovium atoms have ever been made and they decay very quickly, so it is never handled in an ordinary laboratory.
