Textbooks only ever mention covalent bonds between silicon and oxygen atoms in silica. However, as electron movement is random, one end of a silicon atom in a given instant could be more positive than the other (setting up a temporary dipole) and this temporary dipole could induce dipoles in neighboring oxygen/silicon atoms. Could somebody confirm if this is indeed the case?

3Temporary dipoles form *everywhere*. – Ivan Neretin Jun 18 '19 at 12:12

1Temporary dipoles are induces even by other temporary dipoles, not talking about permanent dipoles. – Poutnik Jun 19 '19 at 08:08
