[請問]關於同位素的問題...
Element A is found in two allotropic forms, with allotrope A1
being thermodynamically more stable than A2 under normal conditions.
請問以下這個敘述對嗎??
Allotrope A2 cannot occur naturally but must be made in laboratory
我的解答寫"對"
但我的問題是
很多元素的同位素不都可以自然存在於自然界中嗎?
像海水中也有氘、氚
所以...請問是我觀念錯...還是...他答案有問題??
題目出自中山大學89年化學所入學考
有勞各位高手了...謝謝
