Nuclear Nomenclature XA Mazs number (no.ofn+no. of p) Z YAtomic no. (no. of protons) No. of neutron = A-Z Classification of nuclei→ 1. Isotopes Same "Atomic noz but diff. mass no. A : eg., H', 142, 143 If zis same then element will be same. 2. Isobars Same A but diff. z eg. 16014 and yuly 2-diff. thes 7 element will be diff. 3. Isotone Same no. of neutron. C13 and N=13-6-7 7N14 N=14-7=7 eg. 4. Isomers Nuclei having Same A and same z but different from one another in their nuclear energy states. eg. XA Z z ^ (X ^ A -> Y) 3 ^ L; +r L 3 lehuston) اگریزی Also these nuclear energy states have diff. life timex. S Mirror nuclei→ Also 1 Same A but different z proton and neutron muniber interchargele eg. 4B * e ^ 7 and 3 ^ (4 ^ 7) z = 4 N = 3 N = 4 (All) z = 3 Every Mirror muclei arre isobar, but All isobar need not be mirror nuclei.. Mirror nuclei special Care of iso bary. For mirror nuclei which (A = Odd) A = 22 plus/minus 1 g. 4 Be and 3 ^ (4 ^ 7) A = 7 = 2 * 4 - 1 A = 7 = 2 * 3 + 1 Alpo- A180 A = z_{1} ^ 2 - z_{2} ^ 2 )(z 1 >z 2 ) A = 7 = 4 ^ 2 - 3 ^ 2 Z_{1} - Z_{2}*z plus/minus 1 ⇒4-3= +1 3-4-1
