Thank you for promoting standardization. Not all things in life need a reason, but standardization helps different divisions of the scientific community (be it different departments, institutions or even countries) to work as efficiently as possible and avoid miscommunication.

the electronic configuration for chroumium was wrong I guess. it has to be 4s1 3d5

This is gonna help me pass my physics exams

Great video! I have a test on tuesday with molecular orbitals and bond order/length. If you have a video on that topic ready to post that would be amazing, your content always helps me, so thank you.

Great tutorial but, the final example is incorrect. be warned there are exceptions to the diagonal rule, chromium is one of them, its e- configuration is [Ar] 3d⁵ 4s¹, not what is shown at 21:53.
