Seaborgium Bohr model: diagram and electrons per shell

The seaborgium Bohr model shows a seaborgium atom (Sg) 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, 12 in shell P and 2 in shell Q. This page has a rotating 3D seaborgium 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 seaborgium (Sg), a simplified picture of a single seaborgium atom. Its nucleus holds 106 protons, and a neutral seaborgium atom has 106 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, 12 in shell P and 2 in shell Q).

Seaborgium Bohr model diagram

Bohr model diagram of seaborgium: a nucleus of 106 protons with 106 electrons on 7 shells, 2 in shell K, 8 in shell L, 18 in shell M, 32 in shell N, 32 in shell O, 12 in shell P and 2 in shell Q, each ring labelled with its shell letter. — The seaborgium 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, 12 in shell P and 2 in shell Q).

Seaborgium electrons per shell

A neutral seaborgium atom has 106 electrons, one for each of its 106 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, 12 in shell P and 2 in shell Q.

How the seaborgium Bohr model builds up, shell by shell

Watch the seaborgium 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, 12 in shell P and 2 in shell Q) as it forms.

Animation of the seaborgium Bohr model being built: a nucleus of 106 protons appears first, then each shell grows in around it and takes its electrons, giving 106 electrons on 7 shells (2 in shell K, 8 in shell L, 18 in shell M, 32 in shell N, 32 in shell O, 12 in shell P and 2 in shell Q). — The seaborgium 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, 12 in shell P and 2 in shell Q. Protons are red, neutrons yellow and electrons blue.

How to draw the seaborgium Bohr model

Find the atomic number. Seaborgium has atomic number 106, so a neutral atom has 106 protons and 106 electrons.
Draw the nucleus. Put a circle in the centre and write Sg in it. The 106 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, 12 in shell P and 2 in shell Q.
Check the total. 2 + 8 + 18 + 32 + 32 + 12 + 2 = 106, the atomic number, so every electron is accounted for.
