principal energy levels in atomic physics
An electron shell is a region around an atom's nucleus where electrons can be found, with each shell corresponding to a specific energy level. Understanding electron shells matters because they determine how atoms bond with each other and behave chemically.

電子層,或稱電子殼或電子殼層,是原子物理學中,一組擁有相同主量子數n的原子軌道。電子層組成為一粒原子的。這可以證明電子層可容納最多電子的數量為(但當第一層電子為倒数第一层只能容纳2个;倒数第1层只能容纳8个,倒数第2层只能容纳18个),這種全滿的電子層稱為「閉合殼層」。 亨利·莫塞萊和查尔斯·巴克拉的X-射線吸收研究首次於實驗中發現電子層。巴克拉把它們稱為K、L和、M(以英文字母排列)等電子層。這些字母後來被n值1、2、3等取代。它們被用於分光鏡的。 電子層的名字起源於波耳模型中,電子被認為一組一組地圍繞著核心以特定的距離旋轉,所以軌跡就形成了一個殼。
