1. 唔同element atom既proton/neutron/electron既質量係咪一樣? 例如
fluorine atom既proton同iron atom既proton質量會唔會唔同
2. 點解要用carbon-12 scale黎搵一粒atom既質量 而唔可以用
oxygen-16 scale呀hydrogen-3 scale黎搵?
關於化學既兩個問題(中三，唔該盡快)

✔ 最佳答案
1. proton, neutron and electron of different atom is the same.the difference in chemical activity is due to different in the
number of proton in an atom.
2. carbon-12 is very abundant in the world. many organic
and inorganic compounds contain carbon atoms.
so it is used for comparison.
