Question
Find the energy in $\mathrm{eV}$ required to remove the remaining electron from a doubly ionized lithium $\left(\mathrm{Li}^{2+}\right)$ atom.
Step 1
A lithium atom has 3 electrons. When it is doubly ionized, it means 2 electrons are already removed. So, only one electron is remaining and that is in the ground state (n=1). Show more…

Find the energy in electron-volts required to remove the remaining electron from a doubly ionized lithium (Li $^{2+}$ ) atom.
The lithium atom has a nuclear charge of $+3 e$. Find the energy required to remove the third electron from a lithium atom that has already lost two of its electrons. Assume the third electron to be initially in the ground state.
Calculate the ionization energy of doubly ionized lithium, Li$^{2+}$, which has $Z = 3$ (and is in the ground state).
