Inorganic Chemist | Educator | Mentor | AI Advocate & Design Expert. I'm a chemistry professor, and I build free tools that help students learn chemistry by doing, not memorizing: BondWorks for bonding and naming, and ElementWorks, an interactive periodic table, at stem.oweini.com. They have no ads and no sign-up. If they've helped you, a coffee helps me keep building more (CalcWorks is next). Thank you!
