把图也要化出来

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)

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
