I love the variety of options for bond length/types. I can make classic ball/stick models or more condensed versions. The bond angles are incredibly helpful for visualizing configuration, and I'm already getting a lot of use from this kit! Also, the ability to rotate around single bonds of all types is really appreciated! 10/10! Read more

As a visual learner, this really helped me through organic chemistry to illustrate reaction mechanisms and bond formation Read more

Great set. lots of possibilities. Used to have Styrofoam tetrahedron in college. just love the three dimensional relation between elements. Read more

I teach properties of natural gas. It is good for visual learners. Read more

I will be using these for my orgo course, only thing is the molecules look a little too big but that may be the standard I'm not sure yet. Read more

bought these at the suggestion of my professor. (not the specific brand, just “get a 3d modeling kit if you can’t visualize it” type of thing). It’s pretty awesome for so cheap. MOST of the carbons have 4 bonding sites, but some have 3, and there are 2 with just 2 bonding sites (i’m assuming triple bond + another bond). most of the other bigger atoms are like this, in that they have less than 4 bonding sites (sulfur, nitrogen.) For oxygen there is only one with 4 bonding sites, but most are with two bonding sites- i think leaving us to assume it has its normal valency of 2 bonds and 2 lone pairs. there are also some oxygens with only one bonding site. i think it came with 60 hydrogen atoms? these, and well as the fluorine atoms, are smaller than the rest. it comes with a guide with the exact numbers of all the pieces, as well as a bonus stencil for shapes like hexagons, octagons, and a lot of other things. i definitely recommend! the material is good quality too.

Buen producto, solamente la caja frágil, debería venir en un empaque con mayor cuidado Read more
