经典电磁理论认为,原子由原子核和核外电子组成,电子在库仑力作用下绕核做圆周运动.特别是氢原子,核外电子绕氢核的运动可看成是匀速圆周运动.关于氢原子及核外电子的运动模型问题,涉及圆周运动、静电力、电势能、等效电流等知识,现将此类问题归类拓展如下. Classical electromagnetic theory that the atom by the nuclear and extranuclear electrons, the electron under the action of Coulomb force around the core to do circular motion, especially hydrogen atoms, extranuclear electrons around the proton movement can be seen as a uniform circular motion. About hydrogen atoms And extranuclear electron model of motion, involving circular motion, electrostatic force, potential energy, equivalent current and other knowledge, is now expanding the classification of such problems are as follows.
