Answer: Arsenic ( As ) is a Diamagnetic What is Paramagnetic and Diamagnetic ? A few atoms of the new element 113 were created in 2004 by a team of Russian and American scientists. Paramagnetism is due to the presence of unpaired electrons in the material, so most atoms with incompletely filled atomic orbitals are paramagnetic, although exceptions such as copper exist. not exited .. In fact, diamagnetic substances are weakly repelled by a magnetic field as demonstrated with the pyrolytic carbon sheet in Figure \(\PageIndex{2}\). Generally, strong delocalization in a solid due to large overlap with neighboring wave functions means that there will be a large Fermi velocity; this means that the number of electrons in a band is less sensitive to shifts in that band's energy, implying a weak magnetism. E. As, An atom of which of the following elements has the smallest ionization energy? An external magnetic field causes the electrons' spins to align parallel to the field, causing a net attraction.
