Diamond and silicon oxide have a similarity in terms of structure and bonding. State it?

Both diamond and silicon oxide have a covalent bonding structure. In diamond, each carbon atom is bonded to four other carbon atoms in a tetrahedral arrangement, forming a strong and rigid three-dimensional network. In silicon oxide, each silicon atom is bonded to four oxygen atoms in a similar tetrahedral arrangement, creating a network of interconnected silicon and oxygen atoms. This covalent bonding structure gives both diamond and silicon oxide their hardness and stability.
