Imagine removing one electron form He^(4) and He^(3). Their energy levels, as worked out on the basis of bohr model will be very close. Explain why. |
| Answer» Solution :Imagine ONE electorn removed form `._2He^(4) and _2He^(3)`. As both the residual NUCLEI are very heavy compared to the mass of ELECTRON removed, therefore, their energy LEVELS, WORKED out on the basis of bohr model, will be very close. | |
