如果simple molecular struction ge compoud裏面分成2層,即係molecule==>atom
eg. Each molecules in water contains 1 oxygen atom and 2 hydrogen atoms
咁如果ionic compound分成2層, 係 x=>ions
Each x in Sodium Chloride contains 1 sodium ion and 1 chloride ion
我想問x係咩????????

x = formula unit (式單位)
Formula unit is based on the chemical formula of the ionic compound.
For example, the formula unit of NaCl contains 1 Na+ ion and 1 Cl- ion.
One mole example, the formula unit of Al2O3 contains 2 Al3+ ions and 3 O2- ions.
