Step 2a: Check if the given is an Ionic compound's property. These 3 types of bonds (covalent, ionic, and metallic) make up what are called intramolecular bonds (Notice the first 5 letters: INTRAmolecular bonds). If I'm understanding correctly, the more common definition of molecule where even covalent compounds that have more than one type of element in them, for instance propane and formaldehyde would simply be considered "molecules?". Looking at the periodic table, to which element classes do potassium and chlorine belong to? Worked example: Finding the formula of an ionic compound - Khan Academy The metallic bonds form between two or more METALS. Molecules and compounds Google Classroom Compounds can be classified as ionic or covalent. The positive cations and the negative anions then attract each other to form ionic bonds. Ionic and Metallic Bonding Review A)Electrons are shared and the bonding is ionic. The three types of van der Waals forces include: 1) dispersion (weak), 2) dipole-dipole (medium), and 3) hydrogen (strong). the caffeine molecules, to the decaffeinating machines, which use liquid solvents to remove this stimulant from some of the beans.
