The numbers of α and β particles emitted in the transformation 92U238 → 92U234 : (a) 2, 1 (b) 1, 2 (c) 1, 1 (d) 1, 0 |
| Answer» <p style="text-align: justify;"><span style="font-family:Arial,Helvetica,sans-serif"><strong>Correct option (b) 1, 2 </strong></span></p><p style="text-align: justify;"><span style="font-family:Arial,Helvetica,sans-serif"><strong>Explanation:</strong></span></p><p style="text-align: justify;"><span style="font-family:Arial,Helvetica,sans-serif">Change in mass number = 4 a.m.u. Change in atomic number = No change</span></p><p style="text-align: justify;"><span style="font-family:Arial,Helvetica,sans-serif">∴ α particle = 4/4 = 1</span></p><p style="text-align: justify;"><span style="font-family:Arial,Helvetica,sans-serif">Change in atomic number due to α particle = 2 hence, 2β particles emitted.</span></p> | |
