multiple choice 10 points
what is the iupac name of the base csi?
cesium iodine
cesium iodide
iodine cesiumide
cesiumide iodide

Explanation:

IUPAC naming for binary ionic compounds (like CsI) follows the rule: cation name + anion name. Cesium (Cs) is the cation. For the anion (I), the element name (iodine) is changed to -ide (iodide). So it's cesium iodide.

Answer:

cesium iodide
