  Motivated by recent numerical relativity simulations of charged black holes
and their interactions, we explore the properties of common slicing conditions
in Reissner-Nordstr\"om spacetimes. Specifically, we consider different choices
for the so-called Bona-Mass\'o function, and construct static and spherically
symmetric slices of the Reissner-Nordstr\"om spacetime satisfying the
corresponding slicing conditions. For some of these functions the construction
is entirely analytical, while for others we use numerical root-finding to solve
quartic equations. Our solutions are parameterized by the charge-to-mass ratio
$\lambda = Q/M$ and approach a unique slice, independent of the Bona-Mass\'o
functions considered here, in the extremal limit $\lambda \to 1$.
