Bohr Model Maker
Use a Bohr model maker to create an introductory atom diagram with a nucleus, shells and electrons. Name the element and electron count before drawing, and treat shell capacity as a simplified classroom model rather than a complete quantum description.

Tool overview
Explore the use cases, workflow, and key things to know.
Name the atom
Specify the element and electron count so the shell sketch has a defined scope.
Separate nucleus and shells
The nucleus contains protons and neutrons; electrons are shown in surrounding shells.
State the model limit
Bohr shells are a useful introductory representation, not a complete description of electron behavior.
Concept reference
Bohr model reference: nucleus, shells and electrons
This reference shows a generic atom with protons and neutrons in the nucleus and electrons arranged on two shells. It is a simplified teaching model: it does not show orbitals, electron probability clouds or a measured atomic radius.
Bohr model label key
Use the reference and definitions together. On a small screen, scroll the table horizontally.
| Part | Role in the model | Drawing check |
|---|---|---|
| Proton | Positive particle in the nucleus | The proton count identifies the element in a neutral atom. |
| Neutron | Uncharged particle in the nucleus | Neutron count can vary among isotopes; do not infer isotope from a generic sketch. |
| Electron | Negative particle shown on a shell | A neutral atom has equal proton and electron counts. |
| Shell | A simplified energy-level ring | Shell diagrams are not literal circular planetary orbits. |
| Valence shell | The outer occupied shell in the sketch | Use it to introduce bonding patterns, while acknowledging the simplified model. |
Use a Bohr model for the right chemistry question
A shell diagram is useful for counting and introducing valence electrons. It should be paired with a clearer orbital model when the lesson moves to quantum mechanics or molecular structure.
Count before drawing
Set the atomic number and charge, then determine the electron count.
Use shells as a convention
The rings organize an introductory explanation; they are not paths measured in space.
Connect to bonding carefully
Valence electrons help introduce reactivity, but real bonding requires a more complete model.
Common Bohr model mistakes
Wrong electron count
Charge changes electron count, while atomic number fixes proton count.
Planetary interpretation
Electrons are not tiny balls traveling on measured circular tracks.
Overfilled sketch
Use the shell convention appropriate to the element and lesson; do not force every atom into two rings.

- 1
Set atomic facts
Choose element, charge, proton count, neutron count and electron count.
- 2
Place shells
Arrange electrons using the classroom shell convention required for the lesson.
- 3
Review the limits
Check the count and add a note about the simplified representation.
A prompt you can adapt
Create a clean, editable Bohr model for a named neutral atom. Show a labeled nucleus with protons and neutrons, place the correct number of electrons on simplified shells, identify the valence shell, and add a note that this is an introductory model rather than a full orbital description.

What does a Bohr model show?
It shows an atom with a nucleus and electrons arranged in simplified energy-level shells.
How do I know the number of protons?
The atomic number equals the number of protons.
How do ions change the model?
An ion has gained or lost electrons, so its electron count differs from its proton count.
Is a Bohr model scientifically complete?
No. It is an introductory model; orbital diagrams and quantum descriptions provide more detail.
Can I edit the atom diagram?
Yes. Editable Diagram mode lets you change labels, shell positions and electron markers.
