Elements with more than one charge, for the name of the compound, the charge will be indicated by roman letters.
Roman letters will be written after cation.

Rule#1 Elements with more than one charge, charges will be indicated by roman letters.

Elements with more than one charge, for the name of the compound, the charge will be indicated by roman letters Roman letters will be written after cation.

# data[].attributes.body
roman numerials are for cations that has two or more different chares.(e.g. iron can be Iron(II) or Iron (III)

# data[].attributes.body
Rule #1 - Make sure charges of elements balanced out the ionic compound. Thus, it will be neutral.
Rule #2 - Write the formula in the simplest ratio.
Rule #3 - In formula writing, metallic should come first before the non-metallic element.
Rule #4 - Roman numerials are for cations that has two or more different chares

Rule #1, for transition metals, write group number in brackets after metallic element.

# data[].attributes.body
rule 1. the roman number is usually after the cation followed by anion

# data[].attributes.body
Rule 1- element with more than one charge, for the name of the compound, the charge will be indicated by roman letters.
Rule 2- Roman letters only appear after cations.

Rule 1) a) Charges of ions must be balanced to form neutral

compounds.
1) b) The ratio of ions must be in the simplest form.
1)  c)  The simplest ratio of cations to anions is shown in
the chemical formula by subscripts after the

chemical symbol of the element

Rule 2)The name of the cation always comes first, followed by the name of the anion

# data[].attributes.body
1. The first must be a metal and followed by a non-metal.

2. the formula must be in the simplest ratio.

3. charges must be neutral

4.Name of the second compound should be changed to fit the formula

# data[].attributes.body
1)must have the same charges example is like if there is 2- then there must be 2+

2)make it into the simple form and make it neutral compound

Rule one : the charges of the compund must be balanced.
rule two : A metal element comes first before a non mental element .
Rule three: write the formula in the simplest form .

# data[].attributes.body
Rule 1 The charges of the compound must be neutral
Rule 2 the name of the second compound must be changed
Rule 3 Metal compound comes before non metal
Rule 4 If there is only one charge the '1' does not need to b written down

# data[].attributes.body
1: Make sure both charges are the same like + - or 2+ 2-
2:Make sure that the name of the ionic compound ends with -ide like bromide/ chloride

# data[].attributes.body
rule 1:In the equation of the compound  the charge must be neutral
rule 2: In the name of the compound, metal must be first, followed by non-metal
rule 3: If the ratio of the ions is equal, write it in the simplest form

# data[].attributes.body
Rule #1: The charges of the elements must be balanced to form a compound
Rule #2: The chemical formula must be written in its simplest form
Rule 3:

# data[].attributes.body
rule 1. Select to form balanced charged to form neutral compounds.
rule 2. When writing formula, the metal comes first before the non-metal.
rule 3. The name of the metal does not change while the name of the non-metal changes in the formul
rule 4. Write the formula in the simplest ratio.
rule 5.

Rule #1 - Make sure the charges of elements balance out the ionic compound. Therefore, it will be neutral.
Rule #2 - If the charge is 1 then it's not required to write down 1 in the final formula.
Rule #3 - In formula writing, metallic should come first before the non-metallic element.
Rule #4 - In formula writing, the second element's name should be changed accordingly to the charge. For example, Bromide, bromite.
Rule #5 -
