句子理解 1) Metals are electropositive and have a tendency to loss electrons, if supplied
with energy: M ? M+ + e. 金属是电正性的,如果供给能量,有失去电子的趋势。
2) The stronger this tendency, the more electropositive and more metallic an
element is. (元素失电子)趋势越强,其电正性和金属性越强。
3) Thus sodium and magnesium are more metallic than silicon, which in turn, is more metallic than chlorine. 因此,钠和镁的金属性比硅强,以此类推,硅的金属性比氯强。Which 引导非限定定语从句,修饰Silicon
4) Oxides, which are insoluble in water, are regarded as basic if they react with
acids to form salts. 不溶于水的氧化物,如果和酸能够反应生成盐,则认为是碱性的。
5) Weakly electropositive elements are unaffected by water and are much less
readily attacked by acids. 弱电正性的金属不与水反应,且不易与酸反应
6) Salts of strongly electropositive metals have little tendency to hydrolyze and form oxysalts. 强电正性的金属盐水解形成含氧酸盐的趋势很小。
