Question

1. look at the model. then, answer the question and choose the best answer. which energy level has the highest energy? n = 1 n = 2 n = 3

Explanation:

In the Bohr - model of the atom, the energy of an electron in an orbit is given by $E =-\frac{13.6}{n^{2}}\text{ eV}$. As the value of $n$ increases, the magnitude of the energy becomes smaller in the negative - sense, which means the energy of the electron is higher. So, the outermost orbit has the highest energy.

Answer:

'n = 3'
