H atom

Postby Princess Jereza 3C » Sun Oct 27, 2019 10:19 pm

Why do we use hydrogen as the central standard in understanding chemistry?

That's a really interesting question. I think it is because that Hydrogen is a really simple atom with one proton and one electron (which makes examples easier), but I'm curious to hear what other people have to say.

I think it also has to do with that H is the most common element. It has several uses and forms cations very easily.

To make this simpler, one can just look at the ionization energy of the H atom. The H atom has one electron, and so calculating the ionization energy (using coulomb's law) is much much simpler than calculating the ionization energies of atoms with multielectron systems. Although we are not performing rigorous calculations relating to ionization energies, the concept still holds that the simplicity of the hydrogen atom is much better for understanding the fundamental concepts of periodic trends, photelectric effect, etc.
