Electrons are Negative.
Protons are Positive.
Neutrons are No charge.
Molecules are Made of atoms.
Water falls from a reservoir through a channel to a turbine. The water turns the turbines, which allows the generator to make electricity.
An example of force that acts at distance is gravity and an example of contact force is pushing a chair across the room
No. Ionic bonds form when atoms with opposite charges bond with one another. Atoms develop charges by gaining or losing electrons. For a given element, the atoms will (usually) have a tendency to gain OR lose a particular number of electrons, so they can only form ions of a particular charge that is either positive or negative.
