推 Bonniepei:所以是答案錯了嗎? 我答A 答案是C 08/10 19:21
推 Brenner:C沒錯，這段是用兩個預測成功的例子支持預測法則 08/11 09:48
※ 引述《Bonniepei (樂翻天唷)》之銘言：
: 10. It can be inferred from paragraph 3 that the significance of the
: discovery of gallium was that it supported which of the following?
: ○The idea that aluminum was correctly placed in the periodic table
: ○Mendeleyev's prediction that eka-silicon would be discovered next
: ○The organizing principle of the periodic table
: ○The idea that unknown elements existed
: Mendeleyev went further than Meyer in another respect: he predicted the
: properties of six elements yet to be discovered. For example, a gap just
: below aluminum suggested a new element would be found with properties
: analogous to those of aluminum. Mendeleyev designated this element
: "eka-aluminum" (eka is the Sanskrit word for "next") and predicted its
: properties. Just five years later an element with the proper atomic mass was
: isolated and named gallium by its discoverer. The close correspondence
: between the observed properties of gallium and MendeleyeVs predictions for
: eka-aluminum lent strong support to the periodic law. Additional support came
: in 1885 when eka-silicon, which had also been described in advance by
: Mendeleyev, was discovered and named germanium.
: 請問為什麼不是A 答案是C
關鍵在於這一句
The close correspondence between the observed properties of gallium and
MendeleyeVs predictions for eka-aluminum lent strong support to the
periodic law.
在lent strong support to the periodic law.這一句剛好符合
The idea that aluminum was correctly placed in the periodic table
那C的部份似乎找不到相關線索因為gallium的出現並不能證明The organizing principle
of the periodic table
