8. What is the major difference between the Bohr model and the currently accepted atomic model? Bohr assumed that electrons have very little mass.
Bohr assumed that electrons could be found within an electron cloud.
Bohr assumed that the nucleus was positive.
Bohr assumed that electrons move in fixed orbits.

Ibelieve the answer is b

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
