Crystal structure of naf
WebAccording to Pauling's rules for crystal structures, the allowed size of the cation for a given structure is determined by the critical radius ratio. If the cation is too small, then it will attract the anions into each other and they will collide hence the compound will be unstable due to anion-anion repulsion; this occurs when the radius ... WebFormula and structure: The chemical formula to sodium fluoride is NaF and own molar mass exists 41.99 g/mol. To is a simple doric compound, made the the sodium (Na +) cation and fluoride (F-) anion.The solid salted exists as cubic crystals similar to the crystal structure of sodium dichloride (NaCl).
