几道SAT2化学
1.Which of the following elements would have the largest atomic radius?
A.Cl B.F C.Li D.Ne E.Na ——答案选E.稀有气体和其他元素怎么比原子半径呢?
2.Candles can be safely stored at room temperature,even though their reaction with air is spontaneous at room temperature.——答案是T.那岂不自燃了?
3.A piece of zinc placed in a blue copper nitrate solution will displace the copper from the solution,producing copper metal and a colorless Zn2+ solution.——答案是F.哪错了呢?

几道SAT2化学1.Which of the following elements would have the largest atomic radius?A.Cl B.F C.Li D.Ne E.Na ——答案选E.稀有气体和其他元素怎么比原子半径呢?2.Candles can be safely stored at room temperature,even though their r
1.Na是第三周期元素,其他都是第二周期,哪怕是稀有气体也一样.
2.我想题的意思是能在室温下点燃蜡烛,除此之外实在想不到别的原因了.
3.producing copper metal 错,Cu在酸性条件下会与NO3-发生氧化还原反应,生成Cu2+与气体NO2.

电子层数多，半径大，则排除B.C.D，核电荷数少，则半径大，故排除A

同周期的越靠前半径越大，下一周期的比上一周期的半径都要大
