Physical Chemistry Doubts

These were some of the doubts that occurred to me while studying a physical chemistry book. Would be helpful if somebody enlightened me on:- 1) Ferromagnetic substances(Explain them)? 2) Spin Statistics theorem for He atom? 3) Hamiltonian operators for H atom?

Could someone post the answer. Would be helpful for others as well!!

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

$Ferromagnetism$ -: physical phenomenon in which certain electrically uncharged materials strongly attract others. Two materials found in nature, lodestone (or magnetite, an oxide of iron, Fe3O4) and iron, have the ability to acquire such attractive powers, and they are often called natural ferromagnets. $Source >>$ this

Hey Tsar, can you say a little more about what is confusing about you with these topics?

Josh Silverman Staff - 6 years, 8 months ago

@josh silverman I came across these terms and I couldn't understand them so I was hoping if somehow could explain them for me.

Have you studied quantum mechanics yet?

Josh Silverman Staff - 6 years, 8 months ago

@Josh Silverman – No. But have done structure of atoms.

If you want to understand ferromagnetic substances, watch this video.
