  • question_answer Imagine removal of one electron from \[H{{e}^{4}}\] and \[H{{e}^{3}}.\] Their energy levels, as worked out on the basis of Bohr model will be very close. Explain, why.

    Answer:

    On removing one electron from \[H{{e}^{4}}\] and \[H{{e}^{3}},\] the energy levels, as worked out on the basis of Bohr model will be very close as both the nuclei are very heavy as compared to electron mass. Also after removing one electron from \[H{{e}^{4}}\] and \[H{{e}^{3}}\] atoms contain one electron and are hydrogen like atoms.
