If you are going up a hill instead of a ladder, your energy expenditure is not quantized. Thus, in climbing the ladder, your expenditure of energy is quantized. If the available energy is only enough to move partway up to the next rung, you cannot move at all because you cannot stop between rungs. To move upward, you must use enough energy to move your feet to the next higher rung. The energy needed to climb the ladder is used in finite amounts to lift your body from one rung to the next. If you are climbing a ladder, you can stop only on the rungs you cannot stop between them. Thus, the dispensing of soft drinks byĮnergy can also be quantized. Soft drinks dispensed by a machine are available only in You cannot buy a half or a third of a can of soda you can buy only a wholeĬan or several cans.

If you are buying a soft drink from a machine, you can buy only a certain amount. If you are pouring a softĭrink from a can, you can pour out as much or as little as you like. If it is available only in multiples of a set amount. What does this statement mean? A property is quantized In describing these regions of space, we also recognize that the energy Regions around the atom's nucleus within which the electron may be found.Ģ. In how precisely we can mark its position at any instant. Because of the electron's small size and high energy, we are limited Its most probable location from the nucleus. The higher the energy of an electron in an atom, the farther is The energy of an electron depends on its location with respect to the nucleus By studying these spectra, scientists have drawn various conclusions about the behavior of electrons in atoms.ġ. The lines in the spectrum of an element represent changes in the energy of electrons within the atoms of that element. The energy of an electron is of the same order of magnitude (is in the same range) as the energy of light.
