我完全5明molecules 係咩嚟...

本書話molecules in compounds 同elements ...

molecules in compounds 係咩嚟?本書話compounds made upf non-metals only usually consist of neutral particles called molecules. compounds 5係由2個 or 更多atom 組成ga 咩?點解冇la la 關molecules 事? 有人話molecules 係由同1種atom 組成,更點解water molecule 係made up of 2atom? 如果molecule 係made up of 2 atom, 咁同compounds 有咩分別? ionic compounds 同molecular compounds 有又咩分別?

molecules in elements 又係咩嚟?係5係 metals 就係atom, non-metals 就係molecules?

5該各位盡量用d簡單d嘅字解釋...萬分感謝~ T^T

✔ 最佳答案

molecule(分子) 呢樣野的確很容易誤解
其實分子呢樣野並不需要由什麼高深的化學理論去定義
分子顧名思義就是一個compound/element入面的最少單位
例如水的分子就係H2O 氧氣的分子就係O2
簡單的比喻就係一堆磚頭砌埋變成compound/element
而一個磚頭就叫做分子molecule
至於molecules in compound就係果堆磚係compound ~
in element亦一樣。

至於molecular compound同ionic compound就要較深的知識才能明白，暫時可不必理會。倘若有興趣的話，就看看
