It must have a charge of zero
She will use the periodic table of elements to not only find out the chemical symbols of the elements written within the name, but also to check whether or not the elements are metals and or nonmetals, from this determine the ionic charges if needed for metals, and for metals that have more than one ionic charge, use a Roman numeral to represent the ionic charge that she would be using in writing the chemical formula of the compound.
I believe this process is called fixation
The base is the species that accept hydrogen, and the acids donate hydrogen ions. Dihydrogen phosphite acts as a base and hydrosulfide sulfanide act as an acid.
<h3>What are acids and bases?</h3>
Acids are molecules or chemical species that can donate a proton or a hydrogen ion to another chemical species.
Bases are the ions or molecules that accept a proton or hydrogen ion and release a hydroxide ion.
The acid and base relationship is shown as,
