The video explores whether potassium carbonate (K2CO3) is ionic or covalent. It explains that K2CO3 is an ionic compound overall, with ionic bonds between potassium ions and the carbonate ion. However, within the carbonate ion, the bonds between carbon and oxygen are covalent. The video discusses the periodic table, highlighting that metals and non-metals typically form ionic compounds. It also covers the ionic charges of potassium and carbonate ions, explaining how they balance to form a stable compound.
