These tetrahedral sp3 carbon atoms are used in every Molymod molecular model sets & kits involving organic molecules. You can buy these atoms separately to build millions of custom models using our 3D Molecular Model Builder. Set the "style" as hybrid dome to see it depicted the same way as the model sets listed below.

Carbon is such a versatile element that almost 10 million (known) different carbon compounds exist 1. We include 14 of the sp3 carbons in our most popular Student Organic Chemistry Model Set & 20 in our Ultimate Student Organic Chemistry Model Set.

The uniqueness of carbon comes from the fact that it can bond to itself in many different ways; in straight chains, branched chains and rings. It can also bond singly, doubly and triply to itself. The chemical basis of all living organisms is linked to the way that carbon bonds with itself and other atoms 2.



1) Organic compounds.

2) Carbon chemistry.

Our 5x5mm Nd magnets are compatible with this atom & can be used to build our AtoMag™ magnetic molecular models or custom magnetic molecular models.

Making ethanol models as gifts. Who knew ethanol looks like a dog? Also it's a great product, everything went together well.

Better to hand out models of ethanol than "hair of the dog" hangover cures! Thanks for letting us know.


No way could I make a ball with four evenly-spaced (tetrahedral) branches, but Indigo had them for me at a reasonable price. I needed a bunch of them, too. They came in a matter of days and meet my needs perfectly for illustrating a carbon atom. I just wish they had given the holes dimension, so I would have known exactly how they would connect with other pieces ahead of time (which BTW, are 3/16 inch diameter).

— Don
— Indigo:

Actually, the holes are 5mm & you can press our 5x5mm Nd disc magnets into them. We were able to make some interesting magnetic models this way. What we think is the best cyclohexane chair-boat, chirality demonstration & so on.
