Therefore, O has 2 unpaired electrons. Diamagnetic Levitation occurs by bringing a diamagnetic material in close proximity to material that produces a magnetic field. Noble gases rarely form compounds and they don't exist as molecules in their pure form. 2– = [Ne] Cl – = [Ar] Na + = [Ne] Mg. 2+ = [Ne] Ga. 3+ = [Ar]3. d. 10. 6. s. 2. Indicate whether boron atoms are paramagnetic or diamagnetic. U Transition element ions are most often paramagnetic, because they have incompletely filled . true. KCET 2010: Peroxide ion a) is diamagnetic b) has five completely filled antibonding molecular orbitals c) is isoelectronic with neon d) has bond order Diamagnetic means that its outer valence shell has NO unpaired electrons as is the case for Ca with two electrons in its 4s orbital. It is a noble gas. Diamagnetic Levitation. Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air.It was discovered (along with krypton and xenon) in 1898 as one of the three residual rare inert elements remaining in dry air, after nitrogen, oxygen, argon and carbon dioxide were removed. The diamagnetic material will repel the material producing the magnetic field. Generally, however, this repulsive force is not strong enough to overcome the force of gravity on the Earth's surface. In contrast, ferromagnetic and paramagnetic materials are attracted to magnetic fields. Peroxide ion _____ (i) has five completely filled antibonding molecular orbitals (ii) is diamagnetic (iii) has bond order one (iv) is isoelectronic with neon Answer (a): The O atom has 2s 2 2p 4 as the electron configuration. 5. d. 10. Henceforth, we do indeed need to pay attention to question semantics and the phrase ‘regardless of its electronic configuration’. d. subshells. Click here to buy a book, photographic periodic table poster, card deck, or 3D print based on the images you see here! If the substance is placed in a magnetic field, the direction of its induced magnetism will be opposite to that of iron (a ferromagnetic material), producing a repulsive force. First let me make it clear that Ne, which is Neon, is a noble gas. In this case, all electrons are paired and the atom is diamagnetic. Fe. 5.7 × 10^-7 m. diamagnetic susceptibilities for organic molecules as
