✔ 最佳答案
不是!化學作用的定義是"原子最外層電了重新排列", 並不涉及原子核,
而核聚變是4個氫原子組合為1個氦原子的過程, 不能稱之為化學作用, 屬物理
2007-05-18 17:50:58 補充：
下面的弄錯了"化學作用個定義係反應中,有新物質既形成"所謂的新物質是指化合物, 而氦是一種元素(element), 不是化合物(compound)而化合物則是兩個(或更多)原子(atom)用他們的最外層電子(outermost shell)連結(bond)在一起所組成的, 所以化學作用的定義是:原子最外層電了重新排列

係...
因為化學作用個定義係
反應中,有新物質既形成
核聚變有新物質形成==""

No.
Nuclear fusion is the fusing up of light nucleii to form a heavy nucleus in which energy is released from the binding energy (the strong nuclear interaction) of the nucleons.
Chemical raction only invloves orbital electrons, but not nucleons. The energy released is much much less than that given by nuclear fusion.

你也是核聚變?
