Today in the classroom:
First year chemistry is doing a lab modeling how to calculate average atomic mass from isotope data.
Second year chem did their emission spectra data collection yesterday, observing emissions of hydrogen, helium, and neon. They're analyzing that data today. Next week, we'll talk about the deficiencies of the Bohr model and line it up with quantum model (subshells, orbitals, etc).
Today in the classroom:
First year chem students are doing some high-level notes on atomic models and the structure of the atom. Then they'll practice describing atoms based on given subatomic particle data (isotopes, ions, etc)
Second year chem is doing their emission spectra lab today with hydrogen, helium, and neon samples to calculate electron energy changes when excited.

Today in the classroom:
First year chem is finishing their poster/mural project. We'll do atomic structure at the end of class and practice describing atoms tomorrow (protons, neutrons, isotopes, etc)
Second year is entering the weird world of electrons and empirical atomic structure. Today, we're talking wave-particle duality. I've got a laser and we'll look at interference patterns to prep for the emission spectra lab tomorrow.
@brianb It would be a good day to let your high school #chemistry (and #computerscience ) students see that "¡Las Moléculas son Bellas!" https://www.youtube.com/live/Wlp8sqUmQ18

I got tired of white walls so we have murals going up giving basic info for atoms on the periodic table. It's a good brain break for students who are tired of dimensional analysis and quantitative work.

Tokyo’s first subways were but a dream on a drawing board in October 1925. Also, a quarter of a century later in October 1950, nearly 150 students were arrested for a violent protest at Waseda University. https://www.japantimes.co.jp/news/2025/10/01/japan/history/japan-nobel-chemistry-subway-waseda-student-protest-1925-1950-1975-2000/?utm_medium=Social&utm_source=mastodon #japan #history #subway #tokyometro #infrastructure #tokyometropolitanassembly #wasedauniversity #students #studentprotests #lowerhouse #inflation #nobelprize #chemistry #hidekishirakawa
Want cookies to come out crispy? Then don’t bake them with your lasagna! Steam + aromatics = chewy garlic biscuits. A pro baker on MetaFilter explains why (and how cookies were literally the original oven test bakes).

Someone just handed me a box of NMR tubes from shigemi as a brand. They don't exist as a manufacturer anymore. Does anyone know if shigemi tubes (as in the fancy low volume tubes) ever come with rounded bottoms? I've never worked with one and the only pictures I can find are all flat bottom tubes.
I think someone just put a different type of (perfectly adequate, but not $100+ each) tubes in this box and I'd like to confirm. They all say 526-PP which is a wilmad product code.
When an atom loses an electron from the valence shell, it has a positive charge and becomes a cat-ion

If anyone in the ChemiVerse is on bluesky I apparently got responses there, but from people who didn't bridge their accounts (so they saw my post about the NMR tubes but I can't see theirs to reply to from here), could you let them know they need to bridge?
I do appreciate the responses, they were interesting (particularly since shigemi apparently still exists, just not still at the website listed on the box sitting on my desk!).
