The Atom
... Electrons are negatively charged and matter is neutral. If the electrons are so small, what accounts for the rest of the mass in a typical atom? JJ Thomson proposed a model of atom to answer these questions. The model consisted of a spherically shaped atom composed of a uniformly distributed pos ...

... Some atoms or molecules in their neutral gaseous state have an affinity to acquire a free electron and form a stable negative ion. This property of negative ion formation is known as 'electron attachment' or 'electron affinity'. It has been proved that the atomic or molecular gases having electron a ...

... Electrons move not in circular orbits, but in 'fuzzy‘ orbits. Actually, we cannot tell how it moves, but only can say what is the probability of finding it at some distance from the nucleus. Only certain “orbits” or shells of electron probability densities are allowed. The shells are identified by ...

In 1905, Einstein explained this puzzle by resurrecting the particle theory of light. Einstein's ideas were met initially with great skepticism among established physicists. Eventually ...

... Wait…protons are positively-charged AND like charges repel. How do the protons stay together in the nucleus if their charge repels one another? This force is NUCLEAR FORCE. It is the strongest force known. A nuclear explosion occurs when this force is pulled apart. If everything is made of atoms, wh ...
