What causes the attractive forces between particles in matter?
What causes the attractive forces between particles in matter? The particles that make up some matter are close together and vibrate back and forth. If the motion of particles slows the particles move closer together. This is because the attraction between them pulls them toward each other. Strong attractive forces hold particles close together. What […]

You may need to multiply the electrons by the two half-reactions to get the charge to balance out. It’s fine to change coefficients as long as you change them on both sides of the […]
