Cation = negative ion
The roman numeral of a cation indicates he charge of the cation.
The Ionic Charge
roman numerals indicate a number not a letter as such there is no answer to that question
The roman numerals usually indicate the year the show was made.
7,000,000,000 = (((DCC)))C in Roman numerals Numerals in treble brackets indicate multiplication by 100,000 and superscript numerals indicate multiplication by that particular numerals. Hence:- (((DCC)))C = 100,000*700*100 = 7,000,000,000
The roman numeral of a cation indicates he charge of the cation.
The Ionic Charge
the number of electrons lost when forming an ion and that the cation can form more than one cation.
roman numerals indicate a number not a letter as such there is no answer to that question
The roman numerals usually indicate the year the show was made.
6000 = (VI) in Roman numerals because numerals in brackets indicate multiplication by a thousand
A monovalent cation; the symbol is I (Roman).
7,000,000,000 = (((DCC)))C in Roman numerals Numerals in treble brackets indicate multiplication by 100,000 and superscript numerals indicate multiplication by that particular numerals. Hence:- (((DCC)))C = 100,000*700*100 = 7,000,000,000
Roman numerals are used to indicate main ideas, capital letters to indicate major details, and Arabic.
the main ideas
In this case the roman numerals indicate the oxidation state of the cation portion of the polyatomic ion: [Fe(II)O2]2- as opposed to [Fe(III)O2]1- Mn(II)=Mn2+ Mn(VII)=Mn7+
When a cation has more than one possible ionic charge you use either just the number (i.e. 2+) if it is in ion form or a roman numeral (II) in a name.
