A fluorine (F) ion has a charge of 1. An aluminum (AI) ion has a charge of 3+. On a separate sheet of Japer, explain how fluorine and aluminum would exchange valence
electrons to form an ionic compound. Then write the compound's chemical formula and
name the compound.

Movement that is like a t a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. transfers energy from one location to another a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
