5. The salts you tested were held together by ionic bonds. The compounds were made of two types of ions, positive and negative, that were attracted to each other because of their opposite charges. Some ionic bonds take more energy to break. Based on your investigation, which compounds have bonds that require the most energy to break?

Lithium Iodide , Sodium Fluoride, Sodium Chloride, Sodium Bromide , Sodium Iodide, Potassium Fluoride  and Potassium Chloride are the examples of ionic compounds.

Explanation:

Ionic compounds have bonds that require the most energy to break because of strong attractive force between them. According to scientists, about 700 to 4000 Kilo Joules energy is required to break bonds between ionic compounds whereas 800 to 1000 kilo joules energy is needed by the compounds having covalent triple bonds. So ionic compounds needs the most energy to break.
