Atomic mass of 816O is found to be 16.0000u1. what is the mass of 816O

1.	Atomic mass of 816O is found to be 16.0000u1. what is the mass of 816O nucleus (Hint: mass of an electron = 0.00055u)2. determine the total mass of the constituents particles of 816O the nuclei.(Hint : Mass of neutron = 1.00864 u,Mass of proton = 1.007274 u)3. Give a general expression for mass defect and explain what is binding energy?4. Binding energy per nucleon is lower for both very light nuclei (Z ≤ 10) and very heavy nuclei (Z ≥ 70) Justify a nuclear fission and fusion
Answer» 1. Mass of nucleus = (8 × 1.00864 + 8 × 1.007274) amu. 2. (8 × 1.00864 + 8 × 1.007214 + 8 × 0.0055)amu 3. ∆m = [ZM_p + (A - Z) M_n – M) 4. When two light nuclei are combined to form a heavy nucleus, the binding per nucleon increases. Hence the stability of atom increases. When heavy nucleus split into two light nuclei; B.E. for nucleon also increases.

Answer»

1. Mass of nucleus = (8 × 1.00864 + 8 × 1.007274) amu.

2. (8 × 1.00864 + 8 × 1.007214 + 8 × 0.0055)amu

3. ∆m = [ZM_p + (A - Z) M_n – M)

4. When two light nuclei are combined to form a heavy nucleus, the binding per nucleon increases. Hence the stability of atom increases. When heavy nucleus split into two light nuclei; B.E. for nucleon also increases.

A bone containing `200 g` carbon-14 has `beta`-decay rate of `375` decay/min. Calculate the time that has elapsed since the death of the living one. Given the rate of decay for the living organism is equal to `15` decay per min per gram of carbon and half-life of carbon-14 is `5730 years`.A. 22920 yrB. 11460 yrC. 17190 yrD. None of these
Fusion processes, like combining two deuterons to form a He nucleus are impossible at ordinary temperatures and pressure. The reasons for this can be traced to the fact: (a) nuclear forces have short range. (b) nuclei are positively charged. (c) the original nuclei must be completely ionized before fusion can take place. (d) the original nuclei must first break up before combining with each other.
