Why is germanium a good semiconductor? Germanium atoms have one more shell than silicon atoms, but what makes for the interesting semiconductor properties is the fact that both have four electrons in the valence shell. As a consequence, both materials readily constitute themselves as crystal lattices. Substituted atoms alter the electrical properties. Which type of […]

Why does the potential energy increase as the atoms get very close together?
Why does the potential energy increase as the atoms get very close together? For atoms that are very close together, the electrostatic repulsion of the two nuclei dominates. Pushing the atoms closer together works against this force, which is why the potential energy increases. What happens to potential energy when two nuclei approach? The strong […]

Can you separate hydrogen from oxygen?
Can you separate hydrogen from oxygen? Every water molecule includes two atoms of hydrogen and one atom of oxygen. We use a process called electrolysis to break apart water molecules into hydrogen and oxygen. Electrolysis uses an electrical current to split the molecule apart. What happens when electricity touches water? Water is an excellent conductor […]
