Let it be H2- ,H2+ or He2+ ; there's an unpaired electron i.e, they are paramagnetic. Tell whether each is diamagnetic or paramagnetic. When we go back over to "N"_2, since "N" has one less electron than "O" in its atomic orbitals, "N"_2 has two less electrons than "O"_2 in its molecular orbitals. Answer (b): The Br atom has 4s 2 3d 10 4p 5 as the electron configuration. In both cases N 2 and O 2 behave like a magnet. My reference book has this line: $\ce{[PdCl2(PMe3)2]}$ is a diamagnetic complex of Pd(II) Shouldn't it say "paramagnetic"? I have F2^2+ as paramagnetic, but I dont know how to calculate the bond order. C2 species: Use MO diagram with sp mixing that raises energy of σ3> π1; s,p labels changed to numerical labels: Explain why [Ni(NH3)4]2+ is paramagnetic, while [Ni(CN)4]2- is diamagnetic.

Hence, I am unable to grasp the formula correctly. And C2 isn't. Answer (a): The O atom has 2s 2 2p 4 as the electron configuration. (Atomic number of Ni = 28) In [NiCl 4] 2-, due to the presence of Cl - a weak field ligand no pairing occurs whereas in [Ni(CN) 4] 2-, CN - is a strong field ligand and pairing takes place/diagrammatic represenlation. Nd 3+ in CaCl 2 will separate the neodymium ions at large enough distances that they do not interact. So, it will have $2$ unpaired electrons. Diamagnetic atoms repel magnetic fields. Any substances those contain number of unpaired electrons are called paramagnetic substances. B2+ is a Paramagnetic. Is V 3 paramagnetic or diamagnetic? The complex will have $\ce{Pd^{2+}}$ ion, which has a $\mathrm{d^8}$ configuration. If is is C^2+ it would be 1s^2 2s^2 and e⁻s are paired: diamagnetic. Depict high spin and low spin configurations for each of the following complexes. No it is not paramagnetic.O2^2- has 2 electrons more than O2.Pi 2p molecular orbitals get completely filled hence it is diamagnetic. Permalink. Fe+2), then ti is paramagnetic.

For diamagnetic character, there should not be any unpaired electron in the molecules formation. Since it posses 2 unpaired electrons, it is Paramagnetic in nature. Can someone help me. Unpaired electrons will mean that it is paramagnetic. Iron metal has 2 lone electrons. Isn't paramagnetic one arrow and diamagnetic 2 arrow in an orbital? Pay for 5 months, gift an ENTIRE YEAR to someone special! Atoms with all diamagnetic electrons are called diamagnetic atoms. Hence, it can get easily magnetised in presence of the external magnetic field. Species 1 has one valence electron, species 2 has two valence electrons, etc. Please tell me where I am wrong. Now, the ligand NH3 is a strong field ligand and hence it is a low spin complex. Did you notice that Oxygen somehow dances between the poles while Nitrogen escapes? However because there are an even number of electrons in Fe 2+, it is possible that all of the electrons could end up paired in certain situations (see explanation below). If unpaired electrons are present in an ion/molecule, then it is paramagnetic. Water: Diamagnetic. K^+ [Ar] 0 unp e⁻s diamagnetic. Paramagnetic We can work this out by looking at the molecular orbital diagram of O_2 O_2^+ has 1 fewer electron than O_2 which is what gives it the positive charge. "O"_2 is paramagnetic, with one electron each in its pi_(2p_x)^"*" and pi_(2p_y)^"*" antibonding molecular orbitals.

Molecules with one or more unpaired electrons are attracted into a magnetic field. Therefore, the electronic arrangement should be t2g6 eg2 .. Lost your password? Permalink. The electron would be removed from the pi orbital, as this is the highest in energy. Here, for H2 the number of unpaired electron is 0. Answer Save. An atom is considered paramagnetic if even one orbital has a net spin. Salt: Diamagnetic. Here, 10Dqo > P (pairingenergy) and hence all the electrons are paired. An atom could have ten diamagnetic electrons, but as long as it also has one paramagnetic electron, it is still considered a paramagnetic atom. List Paramagnetic or Diamagnetic. Since V3+ has two unpaired electrons, therefore, it is paramagnetic. I hope you have seen the video of the link I had given you in previous post. Answer (c): The B atom has 2s 2 2p 1 as the electron configuration. Iron(III) Paramagnetic (1 lone electron). At 5 K, a small paramagnetic contribution was observed in the field-dependent low-temper-ature magnetization plots (Figure S9). If all electrons are paired, then the ion/molecule is diamagnetic The MO electronic configurations are given. a noble gas). But in all other case there's an unpaired electron. K [Ar] 4s^1 1 unp e⁻ paramagnetic. As^3- [Ar] 3d^10 4s^2 4p^6 0 unp e⁻s diamagnetic . (a) Both A and R are true and R is the correct explanation of A (b) Both A and R are true but R is not correct explanation of A (c) A is true but R is false (d) A and R are false. Removing one electron from the pi orbital still leaves one unpaired electron in the other pi* orbital. Paramagnetic and diamagnetic character of substance depends on the number of unpaired and paired electrons occupied by that substance.
