Result of conjugate symmetry property of DFT


I know one of the properties of DFT for real-valued time series is conjugate symmetry.


But what does it imply? In the textbook it says that for a DFT of the length M, this makes M/2-1 spectral coefficients redundant. Could someone please explain this to me? How do we conclude this?

Apparently the of last four, $\ce{Mg^2+}$ is closest in radius to $\ce{Li+}$. Is this true, and if so, why would a whole larger shell ($\ce{...
