原子八隅體實驗室
Atomic Octet Lab 

拖曳原子建構分子：可在畫布上自由加入、移動原子。

建立鍵結：點兩個原子即可建立單鍵、雙鍵、三鍵。

自動檢查八隅體：系統會計算電子數並判斷分子是否穩定。

一鍵載入常見分子：如水、二氧化碳、甲烷、苯、葡萄糖等。

互動式操作介面：支援縮放、拖曳、刪除、多語言切換。

電腦和手機都可以使用。  手機版：https://sites.google.com/view/earthscienceworld/science/octet/octetphone

Drag atoms to build molecules: Add and move atoms freely on the canvas.

Create bonds: Click two atoms to form single, double, or triple bonds.

Automatic octet check: The system calculates electrons and determines molecular stability.

One-click preset molecules: Load common structures such as water, carbon dioxide, methane, benzene, and glucose.

Interactive interface: Supports zooming, dragging, deleting, and multilingual switching.

Both computers and mobile phones can be used.
