Darmstadtium Bohr model: diagram and electrons per shell

The darmstadtium Bohr model shows a darmstadtium atom (Ds) as a small nucleus with its electrons circling it in 7 shells: 2 in shell K, 8 in shell L, 18 in shell M, 32 in shell N, 32 in shell O, 16 in shell P and 2 in shell Q. This page has a rotating 3D darmstadtium Bohr model, a flat diagram, a table of the electrons in each shell and the steps to draw it yourself.

This is a Bohr model of darmstadtium (Ds), a simplified picture of a single darmstadtium atom. Its nucleus holds 110 protons, and a neutral darmstadtium atom has 110 electrons, arranged around it in 7 shells (2 in shell K, 8 in shell L, 18 in shell M, 32 in shell N, 32 in shell O, 16 in shell P and 2 in shell Q).

Darmstadtium Bohr model diagram

Bohr model diagram of darmstadtium: a nucleus of 110 protons with 110 electrons on 7 shells, 2 in shell K, 8 in shell L, 18 in shell M, 32 in shell N, 32 in shell O, 16 in shell P and 2 in shell Q, each ring labelled with its shell letter. — The darmstadtium Bohr model drawn flat: each ring is a shell, labelled with its letter, and every dot is an electron (2 in shell K, 8 in shell L, 18 in shell M, 32 in shell N, 32 in shell O, 16 in shell P and 2 in shell Q).

Darmstadtium electrons per shell

A neutral darmstadtium atom has 110 electrons, one for each of its 110 protons. They fill the shells from the nucleus outwards: 2 in shell K, 8 in shell L, 18 in shell M, 32 in shell N, 32 in shell O, 16 in shell P and 2 in shell Q.

How the darmstadtium Bohr model builds up, shell by shell

Watch the darmstadtium Bohr model come together: the nucleus first, then each shell in turn, from the innermost outwards, with its electrons joining the ring. The legend names every shell and counts its electrons, so you can read off the arrangement (2 in shell K, 8 in shell L, 18 in shell M, 32 in shell N, 32 in shell O, 16 in shell P and 2 in shell Q) as it forms.

Animation of the darmstadtium Bohr model being built: a nucleus of 110 protons appears first, then each shell grows in around it and takes its electrons, giving 110 electrons on 7 shells (2 in shell K, 8 in shell L, 18 in shell M, 32 in shell N, 32 in shell O, 16 in shell P and 2 in shell Q). — The darmstadtium Bohr model built up in six seconds: the nucleus first, then each shell with its electrons, ending with 2 in shell K, 8 in shell L, 18 in shell M, 32 in shell N, 32 in shell O, 16 in shell P and 2 in shell Q. Protons are red, neutrons yellow and electrons blue.

How to draw the darmstadtium Bohr model

Find the atomic number. Darmstadtium has atomic number 110, so a neutral atom has 110 protons and 110 electrons.
Draw the nucleus. Put a circle in the centre and write Ds in it. The 110 protons sit there with the neutrons.
Draw the shells. Sketch 7 shells as rings around the nucleus. A shell holds at most 2n² electrons: 2 in the first, 8 in the second, 18 in the third and 32 in the fourth.
Place the electrons. Fill from the inside out: 2 in shell K, 8 in shell L, 18 in shell M, 32 in shell N, 32 in shell O, 16 in shell P and 2 in shell Q.
Check the total. 2 + 8 + 18 + 32 + 32 + 16 + 2 = 110, the atomic number, so every electron is accounted for.
