Tennessine Bohr model: diagram and electrons per shell

The tennessine Bohr model shows a tennessine atom (Ts) 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, 18 in shell P and 7 in shell Q. This page has a rotating 3D tennessine Bohr model, a flat diagram, a table of the electrons in each shell and the steps to draw it yourself.

Tennessine Bohr model diagram

Bohr model diagram of tennessine: a nucleus of 117 protons with 117 electrons on 7 shells, 2 in shell K, 8 in shell L, 18 in shell M, 32 in shell N, 32 in shell O, 18 in shell P and 7 in shell Q, each ring labelled with its shell letter. — The tennessine 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, 18 in shell P and 7 in shell Q).

Tennessine electrons per shell

A neutral tennessine atom has 117 electrons, one for each of its 117 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, 18 in shell P and 7 in shell Q.

How the tennessine Bohr model builds up, shell by shell

Watch the tennessine 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, 18 in shell P and 7 in shell Q) as it forms.

Animation of the tennessine Bohr model being built: a nucleus of 117 protons appears first, then each shell grows in around it and takes its electrons, giving 117 electrons on 7 shells (2 in shell K, 8 in shell L, 18 in shell M, 32 in shell N, 32 in shell O, 18 in shell P and 7 in shell Q). — The tennessine 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, 18 in shell P and 7 in shell Q. Protons are red, neutrons yellow and electrons blue.

How to draw the tennessine Bohr model

Find the atomic number. Tennessine has atomic number 117, so a neutral atom has 117 protons and 117 electrons.
Draw the nucleus. Put a circle in the centre and write Ts in it. The 117 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, 18 in shell P and 7 in shell Q.
Check the total. 2 + 8 + 18 + 32 + 32 + 18 + 7 = 117, the atomic number, so every electron is accounted for.
