This principle is commonly, and wrongly, taken to mean that everything on the microscopic level is uncertain. In fact, it implies that the more we try to localize a quantum particle such as an ...

... Atoms that have the same number of protons and electrons are elect ically neutral. However, atoms may gain or lose electrons during chemical reactions. This creates an imbalance of negative and positive charges. Atoms may have a negative charge because they have gained extra electrons. Such atoms ar ...

This means every object has potential energy, even though some have more than others. Once we harness electrical ...
