Hey everybody, @madeleine_ here! I'm a huge bio and chem nerd and I'd LOVE to knot a keychain of a molecule called a benzene ring! The shape is pretty simple, it's just a hexagon with a few extra lines. Here's a link to an image of one: https://freesvg.org/benzene-ringI'd love it if the pattern could be 9-19 strings wide, not counting the borders. The height and width of the pattern should ideally be equal to each other. One slightly tough thing is that the angles inside the ring should be 120 degrees, not 90 degrees. This means that the diagonal lines can't be simple diagonal lines like in #109851 (a beautiful pattern by the way!). If anyone needs some ideas for keywords, here are some that would work well for this pattern: benzene, ring, hexagon, molecule, atom, atoms, carbon, hydrogen, chemistry, chem, ochem, biochemistry, biochem, science, STEM, and school. |

And just in case anyone's curious, here's some info about benzene rings. I'm happy to answer any questions about them, or chemistry in general!Benzene rings are special because they’re really, really stable. I have a longer explanation below, but here’s a shorter explanation for those who know a little about chemistry: Benzene rings are stable because the electrons are relatively delocalized. This means that compared to other molecules, the electrons don't spend time in a particular part of the molecule. Instead, they move all around the molecule without being attracted to a specific area of it. The electrons in benzene rings are delocalized because there are only nonpolar bonds in benzene rings, and because there are adjacent double bonds in benzene rings. The extra lines in the image represent the double bonds. Here's a longer explanation. Hopefully it's understandable to those who don't have a chem background! - Benzene rings are made up of 6 carbons, and each carbon is bonded to 2 other carbons and 1 hydrogen. - They're special because they're really, really stable, and the universe likes stability! - Electrons are teeny tiny particles that (basically) all atoms have. - A certain type of chemical bond (called a covalent bond) is basically when 2 atoms share 2 electrons with each other. - Depending on the atoms, the electrons in a covalent bond might not be shared equally. - If the electrons aren’t shared equally, that means that they're more attracted to one of the atoms than the other. In many molecules, this means that the electrons will be overall more attracted to a particular area of the molecule. - When electrons AREN'T very attracted to a particular part of a molecule, that means the molecule is more stable. - There are only carbon-carbon and carbon-hydrogen bonds in a benzene ring. Electrons are shared equally in these bonds, so this makes the molecule more stable. This part's a little more complicated, and I'm oversimplifying it a bit: - In single bonds, 2 atoms share 2 electrons. But in double bonds, 2 atoms share 4 electrons. - There are also adjacent double bonds in benzene rings. It's a little tricky to explain with words, so I recommend looking at the image to understand what this means. The extra lines in the image are the double bonds. - When there are adjacent double bonds in a molecule, the extra 2 electrons in a double bond can "jump" to a single bond next to the double bond, which means that the double bond has now shifted over. This happens with all 3 double bonds in benzene rings. - The fact that the electrons can shift over means that they won't be spending as much time in a particular part of the molecule, which makes the molecule more stable overall. |

Fun fact: August Kekulé discovered the ring structure of Benzene after having a dream about a snake biting its own tail. (That's like the only thing that I know about the Benzene ring and I think it's pretty cool) |

I've just submitted a pattern, and it includes 2 design variations because I couldn't decide which one looked better😊

I also made two: #116735 (14x14) and #116734 (18x18)
