If we derive it using an addition of an oxygen atom to molecular oxygen ($\ce{O2}$) it will come to be paramagnetic like $\ce{O3}$? B2+ is a Paramagnetic. You can easily predict the magnetic nature of any molecule/atom by its electronic configuration. Paramagnetism: Paramagnetism is the property of the substance that allows it to get attracted towards the magnetic field. Paramagnetic Paramagnetism is a form of magnetism whereby certain materials are weakly attracted by The M.O. You can see that electrons in each energy levels are paired and hence diamagnetic. which o the following diatomic species are paramagnetic and which are diamagnetic? HArepresents the nucleus of hydrogen atom A and HB represents the nucleus of hydrogen atom B.When the two hydrogen atoms approach each other, the following two forces come into existence:(a) Attractive interactions in between:(i)  the nucleus HA an electron eB and(ii) the nucleus HB and electron eA(b) Repulsive interactions in between:(i) electron eA and electron eB and(ii) nucleus HA and nucleus HB.Since attractive forces overpower the repulsive forces, as a result, the enthalpy of the system decreases and a molecule of hydrogen is formed. If the sum of number of electrons in a species are odd number they paramagnetic, if even number diamagnetic (exception O2, B2 - like species having 16 electrons, and 10 electrons respectively. Q. Hence, I am unable to grasp the formula correctly. The two boron atom is B2 molecules are linked by one covalent bond. Is it neutral Oxygen molecule (O2(subsript))? hybrid orbitals lie in a plane and are directed towards the corners of an equilateral triangle with a carbon atom in the centre. Hence the shape is tetrahedral. The central atom (Si) has four bond pairs and no lone pair. The central atoms (As) has five bond pairs and no lon∈ pair. species like B2 are paramagnetic due to presence of two unpaired electrons in pi 2p bonding molecular orbitals according to molecular orbital theory. Discuss. So paramagnetic materials are also diamagnetic, but because paramagnetism is stronger, that is how they are classified. It's worth noting, any conductor exhibits strong diamagnetism in the presence of a changing magnetic field because circulating currents will oppose magnetic field lines. electronic configuration of B2 molecule isB2: [KK (σ2s)2 (σ2s)2 (2px)1(2py)1]Since each 2px and 2py  MO contains unpaired electron, therefore B2 molecule is paramagnetic.

If you want to quickly find the word you want to search, use Ctrl + F, then type the word you want to search. The unhybridized p-orbitals of the two carbon atoms overlap sidewise with each other to form weak pi (. The molecular orbital structure of ethylene: In ethene molecule, each carbon atom undergoes sp, hybrid orbital of one carbon atom overlaps axially with one sp, hybrid orbital of the other carbon atom to form sigma (σ) C - C bond. If the sum of number of electrons in a species are odd number they paramagnetic, if even number diamagnetic (exception O2, B2 - like species having 16 electrons, and 10 electrons respectively . As the two atoms start coming closer to each other, the potential enthalpy continues to decrease (stage B). you need to write the molecular orbital configuration of B2 = [ sigma (1s) ]^2 [ sigma*(1s) ]^2 [ sigma(2s) ]^2 [ sigma*(2s) ]^2 [ π(2px) ]^1 [ π(2py) ]^1. An earthquake of magnitude _________________ on Richter scale has thousand times more destructive energy than an earthquake of magnitude 4. Hence shape is linear.BCl3:The central atom (B) has only three bond pairs and no lone pair. Hence, the shape is trigonal bipyramidal.H2S: The central atom (S) has two bond pairs and two lone pairs. It is opposite to that of the diamagnetic property. In B2 which have electronic configuration 2,3 and atomic number 5 has as you can see 1unpaired electron however on forming covalent bond with another Boron atom it has now shared its unpaired electron and thus has all paired electrons. In the case of the hydrogen molecule, the bond length is 74 pm. Download the PDF Question Papers Free for off line practice and view the Solutions online. hybridisation.
