Sulphur-35 (34.96903 amu) emits a `beta -` particle but no `gamma-` rays, the product is chlorine -35 (34.96885 amu). The maximum energy emitted by the `beta`- particle isA. 0.016767 MeVB. 1.6758 MeVC. 0.16758 MeVD. 16.758 MeV |
Answer» Correct Answer - C Mass defect = mass of sulphur - mass of chlorine `= 34.96903 - 34.96885 = 0.00018g` Binding energy = mass defect `xx 931` `= 0.00018 xx 931` `= 0.1675 MeV` |
