Place in the periodic table
Darmstadtium is element number 110. It sits in period 7 (row 7) of the periodic table, in group 10 (column 10), and belongs to the d-block. Just before it comes meitnerium (109), and just after it comes roentgenium (111). In the same column, platinum is above it. Elements in one column tend to behave alike.
Family: Transition metals.
Physical properties
Too few atoms of darmstadtium have been made to measure its bulk properties. It is expected to be a solid at room temperature.
Inside the atom
An atom of darmstadtium has 110 protons in its nucleus and, when neutral, 110 electrons around it. The electrons are arranged in 7 shells: 2, 8, 18, 32, 32, 16, 2. The outermost shell holds 2 electrons. Written in full, the electron configuration is [Rn]7s2 5f14 6d8 (predicted).
One mole of darmstadtium weighs 282.166 grams, so a single gram contains about 2.13 × 1021 atoms.
The ring picture is a simple model that only counts the electrons in each shell. Real atoms do not look like this.
