what is rbcl
Rubidium chloride is the chemical compound with the formula RbCl. This alkali metal halide is composed of rubidium and chlorine, and finds diverse uses ranging from electrochemistry to molecular biology.ere, the chloride ions form a simple cubic arrangement with chloride anions occupying the vertices of a cube surrounding a central Rb + . This is RbCl's densest packing motif. Because a cube has eight vertices, both ions' coordination numbers equal eight. This is RbCl's highest possible coordination number.
