Water is a simple molecule consisting of one oxygen atom bonded to two different hydrogen atoms. Because of the higher electronegativity of the oxygen atom, the bonds are polar covalent (polar bonds).The oxygen atom attracts the shared electrons of the covalent bonds to a significantly greater extent than the hydrogen …

WebThe proton in a hydrogen atom is a spin one-half charged particle, and therefore possesses a magnetic moment. By analogy with Eq. ( 759 ), we can write (1004) where is the proton magnetic moment, is the proton spin, and the proton gyromagnetic ratio is found experimentally to take that value . WebThe shift of the energy levels of an atom due to a magnetic field is called the Zeeman effect. We say that the curves in Fig. 12-3 show the Zeeman splitting of the ground state of hydrogen. When there is no magnetic field, we get just one spectral line from the hyperfine structure of hydrogen.
