Protons and electrons both carry an electrical charge(电荷). The charges they carry are opposite to each other; protons carry a positive electrical charge while electrons carry a negative electrical charge. Neutrons carry no charge at all. Electricity is the movement of charged particles, usually ...

In Atoms for iPad, kids will explore the smallest particles known to man, with detailed explanations of protons, electrons, and neutrons, the periodic table, and animations explaining the difference between fission and fusion.
In the center of the atom, the protons and neutrons gather to form the nucleus, while the electrons zip around that nucleus as if they are minute planets orbiting their own little sun [source: Northwestern]. A human's body weighing 154 pounds (70 kilograms) is comprised of 7 billion ...
