Good example. It also cover corresponding elergy levels. However pls tell how atoms keep energy or remain in excitation for prolonged time? Is there a tendancy to decay back after excitation & come to their natural/lowest level? Regards.

Eg. an electrons of an atom at lowest energy levels. Still motions are there in an atom.

Good example. It also cover corresponding elergy levels. However pls tell how atoms keep energy or remain in excitation for prolonged time? Is there a tendancy to decay back after excitation & come to their natural/lowest level? Regards. =============================================== Science is the observation, investigation and explanation of natural phenomena. Questions in the form of "how...?" or "why...?" based on your assumptions may have no answer, especially if your assumption is incorrect. How does the Moon stay in orbit around the Earth? Is there a tendency for it to fly off into space? Well, yes there is, and it stays in orbit because gravity keeps it there. So why doesn't it fall to Earth? Because it has a tendency to fly off into space! But we cannot say what gravity *is*, we can only say what it does. This is enough to enable us to launch artificial satellites into orbit, but not enough to say how gravity works. We have to accept that it does. So... what is a "prolonged time"? Why should there be a "natural/lowest" level? Perhaps the natural level is the highest level! Why should 2 be more than 1? How does a chicken lay eggs? Why do you get tears in your eyes when you are sad? Why do you laugh? (Think about it, it's a very silly thing to do, coughing up puffs of air to express pleasure.) Atoms keep energy for a prolonged time because they did NOT change. Tendencies are not certainties, they are instead a statistical measure of a change, there is no guarantee that tossing a coin will come up heads, but one expects it to happen for half of the number of trials IF it is tossed.
