※ 引述《cloudwolf (狼)》之銘言： : ※ 引述《dearvingo (vingo)》之銘言： : : 電子受到原子核的電荷吸引力 為什麼不會掉進去? : ^^^^ ^^^^^^ * 利用中心力場下的波函數計算物體出現的徑向機率時 P = (r^2)RR 會發現在r=0 機率 所以電子不會出現在中心 好像也可以如此解釋 想順道問一下一個關於電子的問題 古典計算電子若擁有h(bar)/2的自旋角動量時 旋轉的速度會約= 137c/2 遠大於光速 而過程中在算classical electron radius時 mc^2 = e^2/4πεr 為什麼要用mc^2 把靜止質能全部換成位能 ??

※ 引述《dearvingo (vingo)》之銘言： : 電子受到原子核的電荷吸引力 為什麼不會掉進去? ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 誰說不會掉進去的 ? 一定會掉進去,只是時間可能會很長 ~ 當然,"掉進去"的定義也要弄清楚. : 除了行星恆星系統古典的理論 有沒有進一步的解釋方法? ^^^^^^^^^^^^^^^^^^^^^ 不用量子力學也有很多解釋(您也可以做一個),不過可能跟恆星系統一樣是錯的.... :為什麼不會崩解? 總是維持著最低有 hω/4π 的基態能量 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 您都把

※ 引述《dearvingo (vingo)》之銘言： : 電子受到原子核的電荷吸引力 為什麼不會掉進去? : 除了行星恆星系統古典的理論 有沒有進一步的解釋方法? : 為什麼不會崩解? 總是維持著最低有 hω/4π 的基態能量 以下是我之前問高手，他解釋給我聽的 可以供你參考 因為原子的尺度大小是由最外圍電子的分布範圍決定的 跟原子核的重量無關 每個最外圍電子所看到的位能因為屏蔽效應的緣故 都差不多 所以最外圍的電子分布不會差很多 另外電子跟原子核會不會產生電位能無窮大或負無窮大的情況 直覺來看 我們可以發現電子在原子核的位置上所出現的機率密度為零 因此不用擔心會撞在一起 如果想要更精確的計算的話 可以利用電子的波函數 下去算所有空間位能的期望值為多少 就馬上可以發現不會有無窮大的情形出現 -
