✔ 最佳答案
有超多元素離子式,其中列出一d常見既離子式:

1+:H+ (hydrogen +ve ion), NH4+ (ammonium), K+ (potassium), Na+ (Sodium), Cu+ (Copper (I) ), Hg+ (mercury (I) )..........

2+:Ca2+ (calcium), Mg2+ (magnesium), Cu2+ (copper (II) ), Fe2+ (iron (II) ), Co2+ (cobalt (II) ), Zn2+ (zinc), Pb2+ (lead (II) )..........

3+:Al3+ (aluminium), Fe3+ (iron (III) )......

1-:H- (hydride), Cl- (chloride), Br- (bromide), NO3- (nitrate), NO2- (nitrite), [O2]- (superoxide)........
2-:[O]2- (oxide), [S]2- (sulphide), [SO4]2- (sulphate), [SiO2]2- (silicate)......
3-:[N]3- (nitride), [PO4]3- (phosphate)......
4-:[SiO4]4- (orthosilicate)......

以下係其中一d離子既顏色 (要有水先至有呢d顏色):

Copper (II): Blue; Cobalt(II): Pink; iron (II): green; iron(III): brown; permanganate: purple; dichromate: orange..........

最活潑既元素係Francium(鈁),佢一遇到水、酸性物質就會爆炸,產生Francium hydroxide(氫氧化鈁),並快速產生大量氫氣。

幅射係由一些結構較唔穩定既原子(如鈾、鈁及大部分人造既元素)產生出黎,分為三種:alpha、beta同gamma,而我地所指既幅射多數係指gamma射線。

Sorry,有野修改:Francium遇到酸性物質係唔會產生francium hydroxide,係產生其他有francium ion [Fr]+ 既鹽

除左樓上果d仲有:
1+ : Ag+(silver ion), Li+(Lithium ion), Rb+(Rubidium ion), Cs+(Caesium ion), Fr+(Francium ion)

2+:Ba2+(Barium ion), Sr2+(Strontium ion), Be2+(Beryllium ion), Ra2+(Radium ion),Mn2+(Manganese(II) ion),Ni(Nickel(II) ion),Hg(Mercury(II) ion)

3+:Cr3+ (Chromium(III) ion)

1-:F- (Fluoride),[ HCO3]-(Hydrogencarbonate ion), [HSO4]-(Hydrogensulphate ion),
2- :[SO3](sulphite), [SiO3]2- (silicate), [CrO4]2- (Chromate ion), [Cr2O7]2-(Dichromate ion)
3-:[P]3- (Phosphide)
