有一些原子序數(shù)沒有已知的對應元素.
(可能是用某些實驗得出了一個元素的atomic number 結(jié)果找不到已知相應的元素 那么有可能就是發(fā)現(xiàn)了一種新元素 或者實驗錯誤)
講的繁瑣一點就是
there have been atomic numbers[←我覺得應該要有s],and there's no known element for such atomic numbers.
atomic number和element之間介詞用for
在這個which的定語從句里面 就把介詞放到which之前
有問題就追問吧
for which這里的 怎么理解 There have been atomic number,for which there is no known element.
for which這里的 怎么理解 There have been atomic number,for which there is no known element.
