For each of the following species, select whether the species is diamagnetic or paramagnetic: 1 2 3 4 5 67 8 9 10 11 12 13 14 15 16 17 18 DiamagneticParamagnetic1 He 5 67 8 9 10 Li Be B CNOF Ne Ca2+ Diamagnetic Paramagnetic 11 12 13 1415 16 17 18 Na Mg 19 20 21 22 2324 25 26 27 28 29 30 31 32 33 34 35 36 K Ca Sc Ti V Cr Mn Fe Co Ni Cu Zn Ga Ge As Se Br Kr 37 38 39 40 4142 43 44 45 46 47 48 49 50 51 52 53 54 Rb Sr Y Zr Nb Mo Tc Ru Rh Pd Ag Cd In Sn Sb TeI Xe 55 56 57 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 Cs Ba La Hf Ta W Re Os Ir Pt Au Hg TI Pb Bi Po At Rn 87 88 89 1 Zn2 Diamagnetic Paramagnetic 58 59 60 61 62 63 64 65 66 67 68 69 70 71 Ce Pr Nd Pm Sm Eu Gd Tb Dy Ho Er Tm Yb Lu 90 91 92 93 94 95 96 9798 99 100 101 102 103 Th Pa U Np Pu Am Cm Bk Cf Es Fm Md No Lr Diamagnetic ParamagneticExplanation / Answer
Be - 1s2 2s2
Since all the electrons are paired, hence the Be is dimagnetic
Ca - 1s2 2s2 2p6 3s2 3p6 4s2
Ca(2+) - 1s2 2s2 2p6 3s2 3p6
Since all the electrons are paired, hence the Ca(2+) is dimagnetic
Cl - 1s2 2s2 2p6 3s2 3p5
Cl(-) - 1s2 2s2 2p6 3s2 3p6
Since all the electrons are paired, hence the Cl(-) is dimagnetic
Zn(+2) - 1s2 2s2 2p6 3s2 3p6 4s2 3d8
Paramagnetic in nature
Cu - 1s2 2s2 2p6 3s2 3p6 4s1 3d10
Paramagnetic in nature
