Question

^{The charges and sizes of the ions in an ionic compound affect the strength of the electrostatic attraction holding that compound together. Based on ion charges and relative ion sizes, arrange these ionic compounds by their expected melting points. Highest melting point MgF2 NaF Mgo KBr Lowest melting point Answer Bank}
