The light-quark $sss$ member of the spin-three-halves <baryon decuplet> has <strangeness> $S=-3$, <baryon number> $B=1$, <flavor hypercharge> $Y=-2$, and <isospin> zero. The <Gell-Mann--Nishijima formula> gives electric charge minus one. Its position at the bottom of the decuplet's triangular <weight diagram> follows by replacing all three up or down quarks with strange quarks.
