Is silica made up of molecules or atoms?
Main point: if there is a metal cation or ammonium ion, it is usually a compound made of ions. If it is a gas or liquid or a low boiling point solid, it is usually a molecular composition, if there are four main refractory substances
There are no metal cations and anions in silicon dioxide. They all consist of silicon atoms and oxygen atoms to see whether they are made up of ions or molecules or atoms
Like carbon dioxide, any molecule is made up of atoms.
