How do the strong acids dissociate?


In writing net ionic equations involving strong acids, one needs to know how strong acids dissociate. For example, the dissociation of $\ce{H2SO4}$:


\begin{align}\ce{ H2SO4 &-> 2H+ + SO4^{2-}\\ H_SO4 &-> H+ + HSO4^{-}\\ }\end{align}



The reason I ask is because apparently the molecular equation


$$\ce{H2SO4 + 2KOH -> 2H2O + K2SO4}$$


has the net-ionic form $$\ce{H+ + OH- -> H2O}$$


It would be helpful if you could describe in general how I should write the dissociation of the strong acids in the net ionic equation.

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{...
