The metal ion - so, if you've got sodium chloride, you'd write sodium first (Na).
The cation, which is the positively charged ion, is written first in a chemical formula for an ionic compound.
Typically in writing an ionic compound, the cation is written first, then the anion.
The cation is written first in the chemical formula for ionic compounds. This is because the cation is positively charged and the anion is negatively charged, so the cation is listed first to indicate the compound's structure.
The element that forms the cation (positive ion) comes first in the formula for an ionic compound.
The ionic compound formula for rubidium thiosulfate is Rb2S2O3.
The cation is written first in the chemical formula for a binary ionic compound.
The cation, which is the positively charged ion, is written first in a chemical formula for an ionic compound.
Typically in writing an ionic compound, the cation is written first, then the anion.
Ba3N2
The cation is written first in the chemical formula for ionic compounds. This is because the cation is positively charged and the anion is negatively charged, so the cation is listed first to indicate the compound's structure.
The element that forms the cation (positive ion) comes first in the formula for an ionic compound.
The negative ion is written second in the formula for an ionic compound.
The ionic compound formula for rubidium thiosulfate is Rb2S2O3.
Platinum (IV) Sulfide
Formula: I-
K2S is the formula for the ionic compound formed from potassium and sulfur.
The last part in the chemical formula of a binary ionic compound is usually the anion, which is negatively charged and is represented by its element symbol. It is written after the cation in the formula to show the complete chemical composition of the compound.
