TPO16 Development of periodic Table - 英檢

(沒PO過幾次文章 有誤請別見怪)

我昨天也在看這題 你參考一下 一開始我也選A 後來看到對岸的解釋

似乎可以接受 你參考看看吧 以下

10. gallium做关键词定位至倒数第三句，但这句话只是说命名为GA，没说支持什么
，往下看说GA的发现支持了元素周期律，而问题刚好是问GA的发现支持了什么，所以答案
是C，元素周期表的组成规律，也就是元素周期律

※ 引述《LucifaChen (Mansun怎麼也這麼好聽)》之銘言：
: ※ 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
