Did anyone else get the periodic table elements that must add up to 200 atoms?
I’m not sure, but I think it was impossible since my captcha included an “Nd”.
You can change the captcha using the refresh button next to it. But Nd is not a problem. Its atomic number is 60. You need to add up to 200. Fm: 100, Zr: 40. I knew that memorizing atomic numbers would pay back some day :P

Ohh, I’m dumb. I mistook atomic number for atomic weight. English is not my first language. Thank you!
