HELP!!!!!!!!!!!!!

Answer 1

Answer:

Using Roman numerals

Explanation:

Distinguishing between the ions of a transition metal in writing involves the use of roman numerals.

A popular case to look at is the element iron.

There are two popular ions of iron. These are the iron 2 and the iron 3 ions

While they differ physically, they can also be differentiation writing.

Iron 3 is written as Fe3+ While Iron 2 is written as Fe2+

Thus, we can write their tetraoxosulphates vi salt name as follows;

For iron ii, we have iron (ii) textraoxosulphate vi while for iron iii, we have iron (iii) tetraoxosulphate vi.

Thus, the use of the roman numerals has helped us in distinguishing between the two types of ions of the same iron
