Configuration [Rn]5f¹⁴6d¹⁰7s²

Atomic weight: 285Da
Phase: liquid, predicted
Density: 14g/cm³, predicted
Melting point: 283K, predicted 10 °C

The outermost shell: the valence electronsThe inner shellsThe nucleus One bead for each electron, on the ring of its shell, counted from the nucleus out. The rings turn at their own pace; the model is Bohr's picture of the atom, which places electrons in shells but not on true orbits.
