Place in the periodic table
Livermorium is element number 116. It sits in period 7 (row 7) of the periodic table, in group 16 (column 16), and belongs to the p-block. Just before it comes moscovium (115), and just after it comes tennessine (117). In the same column, polonium is above it. Elements in one column tend to behave alike.
Family: Post-transition metals.
Physical properties
Too few atoms of livermorium have been made to measure its bulk properties. It is expected to be a solid at room temperature.
Inside the atom
An atom of livermorium has 116 protons in its nucleus and, when neutral, 116 electrons around it. The electrons are arranged in 7 shells: 2, 8, 18, 32, 32, 18, 6. The outermost shell holds 6 electrons. Written in full, the electron configuration is [Rn]7s2 7p4 5f14 6d10 (predicted).
One mole of livermorium weighs 293.205 grams, so a single gram contains about 2.05 × 1021 atoms.
The ring picture is a simple model that only counts the electrons in each shell. Real atoms do not look like this.
