When building an atom, pay close attention to the particles' electrical charges. Protons have a charge of +1. Electrons have a charge of -1. Neutrons are neutral, as its name implies. A stable ...

Therefore, electrons cannot be arranged at random, but they must have fixed levels of energy within each type of atom. Bohr's 'solar system' model of the atom is the way that most people think ...

The size of an atom is only a few angstroms at most - there are 10 billion angstroms in 1 meter. This video also goes the basic parts of an atom (protons, neutrons, and electrons) and why the ...

He suggested that an atom was a tiny solid ball. He published his ideas in 1803. This atomic model has changed over time. Scientists used the model to make predictions. Sometimes the results of ...
