Writing the ion: Na⁺,SO₄²⁻
<h3>Further explanation</h3>Ionic compounds consisting of cations (ions +) and anions (ions -)
The naming is preceded by the cation then the anion with the -ide suffix added
Generally for this ion compound consists of metal elements as cations and non-metals as anions
Metal: cation, positively charged.
Nonmetal: negative anion.
The anion cation's charge is crossed
Example:
Fe₂S₃
Fe charge = 3+
S charge = 2-
The writing of the ionic charge is placed as a superscript behind the molecule/ atom, and the number is written before the positive or negative sign. For a single charge, there is no need to write the number
Example
Cl⁻ (single charge)
Mg²⁺ not Mg⁺²
For the element Na symbol which is group 1A and releases one electron, the symbol writing would be: Na⁺(single charge)
For polyatomic ions, the superscript charge is written after the subscript on the polyatomic element, so it becomes SO₄²⁻
These two ions when combined and bind to Na₂SO₄ (The anion cation's charge is crossed)
if written separately as Na⁺, SO₄²⁻
