With the loss of an electron from $\ce{Li}$ ($\mathrm{1s^2\ 2s^1}$), we get $\ce{Li+}$ ($\mathrm{1s^2}$), then the 2nd shell where the electron had been revolving in $\ce{Li}$ will get disappeared or remain there around the nucleus but empty after the loss of the electron?
I'm actually asking for all the other atoms as well, like generally, are shells constructed already upto the very highest ones containing f orbitals in them and just remain empty when there are no electrons in them?
