Atoms, the smallest particles of matter that retain the properties of the matter, are made of protons, electrons, and neutrons. |
| Protons have a positive charge, Electrons have a negative charge that cancels the proton's positive charge. |
Protons have a positive charge, Electrons have a negative charge that cancels the proton's positive charge. |
| Neutrons are particles that are similar to a proton but have a neutral charge. |
Neutrons are particles that are similar to a proton but have a neutral charge. |
| There are no differences between positive and negative charges except that particles with the same charge repel each other and particles with opposite charges attract each other. |
There are no differences between positive and negative charges except that particles with the same charge repel each other and particles with opposite charges attract each other. |
| If a solitary positive proton and negative electron are placed near each other they will come together to form a hydrogen atom. |
If a solitary positive proton and negative electron are placed near each other they will come together to form a hydrogen atom. |
| This repulsion and attraction (force between stationary charged particles) is known as the Electrostatic Force and extends theoretically to infinity, but is diluted as the distance between particles increases. |

| When an atom has one or more missing electrons it is left with a positive charge, and when an atom has at least one extra electron it has a negative charge. |

| Although atoms are made of many particles and objects are made of many atoms, they behave similarly to charged particles in terms of how they repel and attract. |

| In an atom the protons and neutrons combine to form a tightly bound nucleus. |

| This nucleus is surrounded by a vast cloud of electrons circling it at a distance but held near the protons by electromagnetic attraction (the electrostatic force discussed earlier). |

| When an electron in the conduction band decelerates and falls to another conduction band or the valence band a photon is emitted. |
