What do you think about Feynman's description (http://feynmanlectures.caltech.edu/III_12.html#Ch12-S3) ? It seems to be inconsistent with hyperphysics (http://hyperphysics.phy-astr.gsu.edu/hbase/quantum/h21.html).
The inconsistency is that hyperphysics says that the energy difference is due to spins going from parallel (higher energy) to antiparallel (lower energy) whereas according to Feynman antiparallel spins can be associated also with the higher energy. I don't see how hyperphysics can be correct if one considers also Zeeman splitting like Feynman does in the next section.blue_leaf77 said:try to summarize or point out which part of those long texts that you are concerned with.
Thanks, I think your description is consistent with Feynman's although you are using a slightly different notation. Also, your quoted text above is my summary of what Feynman actually said.blue_leaf77 said:##|F=1,m_F=0\rangle## is a symmetric combination between electron spin up-proton spin down and the opposite. I guess it's this last state which that hyperphysics link has omitted and which Feynman's lecture referred to as "antiparallel spins can be associated also with the higher energy".
The spin of an electron in a hydrogen atom can affect its ground state energy. This is because the spin of an electron determines its intrinsic angular momentum, which can interact with the magnetic field created by the nucleus, leading to a shift in the energy levels of the atom.
Yes, the spin of the nucleus can also affect the ground state energy of hydrogen. The spin of the nucleus can interact with the spin of the electron, resulting in a hyperfine structure splitting of the energy levels in the atom.
The spin of an electron in a hydrogen atom is quantized, meaning it can only have certain discrete values. This is due to the fundamental nature of particles, as described by quantum mechanics. The spin can have a value of either +1/2 or -1/2, and this is what gives rise to the different energy levels in the atom.
Yes, the spin of an electron in a hydrogen atom can be changed through certain interactions, such as collisions with other particles or exposure to magnetic fields. However, the spin of an electron is an inherent property of the particle and cannot be changed by external forces.
The spin of an electron in a hydrogen atom does not significantly affect its chemical properties. This is because the spin is a quantum mechanical property that does not directly relate to the chemical behavior of an atom. However, the spin can indirectly affect the properties of molecules that contain hydrogen atoms, as it can influence the bonding and structure of these molecules.
