Nuclear Nomen clatureXzxAMass number (no of n + no.of p)YAtomic no. (no. of protons)No. of neutron = A-zClassification of nuclei1. IsotopesSame Atomic no Z but diff.:mass no. Aeg. ,H', ,H2,,H3If Z is same then element will be same.2. IsobarsSame A but diff. Zeg. 6c14 and 7 N14Z- diff. thuselement will bediff.3. IsotoneSame no. of neutron.eg. 6C 13 and 7N14 N= 14-7= 7N 13-6=7 4. IsomersNuclei having same Aand same Z but different from oneanother in their nuclear energy states.eg.ZXAZXA + y2%A7(Motor)3Lix73Li+rAlso these nuclear energy states. have diff.life times.5. Mirror nucleisame A but differentzAlso proton and neutron number interctorgesteg.2774 Beand 3 34Z=4N=4N= 3Z=3(All)Every Mirror nuclei are isobar, butAll isobar need not be mirror nuclei. "Mirror nucleispecial case of iso bar%For mirror nuclei which (A= odd)A= 22t1.eg. 4 Be and 34AI 7= 2x4-1 A=7 2%3+1Also-A= Zizz (2,>Z2)A= 7= 42-32Z, Z2 I4-3-+13-4=-1(z-22) 2 = I
