Use the Bohr model to calculate the radius, in angstroms, of a $B{e}^{3+}$ ion with an electron in the $n=5$ state.

Calculate the energy, in joules, of a $B{e}^{3+}$ion with an electron in the $n=5$ state.

$E=$

How much energy would be required to completely remove the electrons from $2\mathrm{.}36$mol of $B{e}^{3+}$ions in the $n=5$ state?

energy to remove electrons:

What wavelength of light would be emitted in a transition from the $n=5$ state to the $n=3$ state of a $B{e}^{3+}$ion?

$=$

What frequency of light would be emitted in a transition from the $n=5$ state to the $n=3$ state of a $B{e}^{3+}$ion?
