Which species is diamagnetic in the ground state

Learning Objective Distinguish diamagnetic from paramagnetic atoms. Key Points Any time two electrons share the same orbital, their spin quantum numbers have to be different. Whenever two electrons are paired together in an orbital, or their total spin is 0, they are diamagnetic electrons.

Atoms with all diamagnetic electrons are called diamagnetic atoms. A paramagnetic electron is an unpaired electron. An atom is considered paramagnetic if even one orbital has a net spin. An atom could have ten diamagnetic electrons, but as long as it also has one paramagnetic electron, it is still considered a paramagnetic atom. Diamagnetic atoms repel magnetic fields.

The unpaired electrons of paramagnetic atoms realign in response to external magnetic fields and are therefore attracted. Paramagnets do not retain magnetization in the absence of a magnetic field, because thermal energy randomizes electron spin orientations. The arrangement of the electrons in the outermost orbital i. A dimagnetic atom has all the electrons arranged in pairs Where as a paramagnetic atom have more than 1 umpaired electrons.

And the magnetic moment of paramagnetic atom can be calculated by the formula. How do you determine if an atom has a diamagnetic ground state electron configuration? Saif Rabbani. Photoelectron spectroscopy.
