Usually the positively charged ion is listed first in a chemical name.
The chemical formula for chlorite ion is ClO2- and the other oxy-anions of chlorine are (IUPAC names in parentheses); ClO- : Hypochlorite ion [ Chlorate(I) ion ] ClO3- : Chlorate ion [ Chlorate(V) ion ] ClO4- : Perchlorate ion [ Chlorate(VII) ion ]
The hydroxide ion's chemical formula is [OH]-
the chemical symbol for boron ion is B+++
The Chemical Formula for Potassium Ion is K+.
Advantages: Common names are easier to remember and recognize compared to chemical nomenclature. They provide insight into the composition or behavior of the ion. Disadvantages: Common names can vary between regions or textbooks, leading to confusion. They may not always clearly indicate the ion's composition.
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.
The cation is always written first in a chemical name. Cations are positively charged ions, while anions are negatively charged ions. The convention is to write the cation first, followed by the anion.
The chemical symbol for a silver ion is Ag+.
The chemical symbol for a sodium ion is Na+.
The chemical formula of a sodium ion is Na+, while the chemical formula of a fluoride ion is F-.
The chemical formula for the hydroxide ion is OH-.
