The ratio of the ions in an ionic compound depends on the charges of the ions. The amount of positive charge must balance the amount of negative charge. For each compound, both the total positive charge and the total negative charge will equal the LCM found in part B. Determine the number of positive ions and the number of negative ions for each ionic compound in the table. Use the ionic charges of each element you found in part A. The number of each ion times the charge on the ion should equal the LCM determined for each cell in part B. [# of ions of an element] × [ion charge] = least common multiple (LCM) Drag each element's chemical symbol to the table to show how many ions are needed to balance the charges. Each symbol will be used more than once. The first row is already completed for you.

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.
