LINKTOR Chemistry Molecular Model Kit (444 Pieces), Student or Teacher Set for Organic and Inorganic Chemistry Learning, Motivate Enthusiasm for Learning and Raising Space Imagination, A Fullerene Set

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.

My son is starting his 3rd year of chemistry and LOVES this kit. He was especially grateful for the stencil to draw molecules type things (like I said HE is the chemistry student, not me).Great tool to help bring bool learning into something you can hold and look at fro many angles. Great teaching tool as well. I love to hear him explain what all the things are and how they work together.Container is nice and keeps everything organized.

It looks like it'll work for my classes. I'll update if I find any issues as a college student. The contents work great; i tried a few configurations before writing this review. I would give it 5 stars but since it came damaged I'm removing a star. They could've used a bubble envelope instead of a slim plastic sleeve. I'm going to have to figure out how to keep the box closed now. The tool is easy to use and I really like the supplemental info it came with. I like that I can reorganize the box if I want.Great value for money, educational value, and I hope any children in my life that come visit can have a fun time playing with them too

They seem to be nice. I’ll update you if it helps my kid pass organic chemistry.

I ordered and count all pieces and found one Bromine (brown ball) missing. Should be 3 and only had 2. Besides that is a great product.

Llegó completo y en buen estado, las instrucciones eran claras, se pudo disfrutar mucho de todo el kit

This 444 piece set seems to be the right size to be able to make many molecules. The appearance seems good and helpful in learning about different elements. The pieces go together easily. This kit has great performance.

Excellent product. Packaged well. Delivered quickly. Sturdy. Teaching chemistry to my kid with this also using this for my chemistry class.
