Hi, I was browsing the definition and translation for 電子 and luckily I found that it meant "electron" (this site is so handy for my research🙂) my eye, however, also fell on the tags. These 3 were all labeled as 'Physics', while I see why, I think most people see these as Chemistry rather than Physics. (I might be biased as a chemist😁), but I think it would be a nice addition if the tag #chem were added to these as well. I'm not suggesting the removal of the physics-tag, but I think both would be nice.
