Using the Periodic Table above that means any compound that contains an element shown in orange will contain ionic (electrovalent) bonds. Compounds that form between two non-metals (or between non-metals and metalloids) will contain covalent bonds.Using the Periodic Table above that means any compound that contains element shown in yellow or green will contain covalent bonds.sing the Periodic Table above that means any compound that contains an element shown in orange will contain ionic (electrovalent) bonds.
