  • Imagine removing one electron from He raies to 4 and He raies to 3. Their energy levels, as worked out on the basis of the Bohr model, will be very close. Explain why.

Imagine removing one electron from He4 and He3. Their energy levels, as worked out on the basis of the Bohr model, will be very close. Explain why.

Answers (1)

One of the biggest limitations of the Bohr’s model of the atom is that it is only applicable for either light atoms having one electron revolving around the nucleus or for H-atoms. The nucleus of these atoms must be positively charged and stationery, such atoms are termed as Ze (called hydrogen-like atom). But if one electron is removed from both He4 and He3, they will fulfil the condition, and the model can be used to find their energy levels.
