鈉的保存方法及原理..

鈉, 英文Sodium, 代號Na (拉丁立natrium的簡寫), 是化學元素之一, 在元素週期表排11, 其原子質量為 22.9898g/mol.
鈉在空氣中很容易氧化. 它和水一接觸就會發生好犀利的化學作用, 釋放出大量熱能. 所以一定要儲存在不含水份的非活反應性(inert)媒體裏, 通常是煤油(kerosene), 以防它在空氣中氧化及和空氣中的水份發生化學作用.

sorry, 拉丁立 = 拉丁文

Na(鈉) should be stored under paraffin oil (煤油) to prevent the contact with water since Na reacts with water vigorously....

These are some vedios of Sodium with water:

呢個睇得清楚D
