如何动态按规则在方形atomic orbitals中布局原子电子？

我需要将原子电子排布为方形轨道结构（常规为均匀圆形分布），要求在方形轨道外围的预设槽位中，根据电子壳层的电子数放置电子，无需手动编写118种原子的布局代码，实现动态排布效果。

参考布局示例 #

• 8电子壳层：填满8个预设槽位
• 7~1电子壳层：按平衡规则减少对应槽位的电子（如17电子需移除垂直中间的一个槽位电子，3电子形成类三角布局）
• 18电子壳层系列：对应18个预设槽位的平衡排布

约束条件 #

• 电子壳层的最大电子数分别为2、8、18、32、32
• 电子必须放入对应壳层的预设槽位（如8电子对应8个槽，18电子对应18个槽），不可沿边缘均匀分布
• 布局需保持平衡性，若存在多种平衡布局，任选其一即可

实现要求 #

可使用等宽字体的x（代表电子）和-（代表空槽位）模拟布局，无需完整前端框架实现，求可动态生成布局的简单算法，而非硬编码118种原子的布局。
