一楼怎么H带负价?楼主我给个口决吧：1价H.Li.K.Na.Ag,2价O.Mg.Ca.Ba.Zn.3Al.4si.5价P.金属易被氧化一般正价非金属反之 23铁24碳17氯35氮硫价常有246铜汞12也都有（例23铁意为铁是变价有2和3价
H He Li Be B C N O F Ne Na Mg Al Si P S Cl Ar K Ca
并不是1～20的元素都能写出例子符号的，要那种容易得电子或失电子的元素才能有离子，也就是活泼的金属或非金属才行。
H-、Li+、N3-、O2-、F-、Na+、Mg2+、Al3+、S2-、Cl-、K+、Ca2＋
H+ He Li1+ Be2+ B3+ C2+ 4+ N3- 2- 0 1-2+ 3+ 4+ 5+ O2- F1- Ne Na1+ Mg2+ Al3+ Si4+ P5+ S2-4+ 6+ Cl1- Ar K1+ Ca2+
H（氢）He(氦) Li（锂）Be（铍）B（硼）C（碳）N（氮）O（氧）F（氟）Ne（氖)Na（钠）Mg（镁）Al（铝）Si（硅）P（磷）S（硫）Cl（氯）Ar（氩）K（钾）Ca（钙）
