  7. Silicon–oxygen bond - Wikipedia

    en.wikipedia.org/wiki/Silicon–oxygen_bond

    A silicon–oxygen bond (Si−O bond) is a chemical bond between silicon and oxygen atoms that can be found in many inorganic and organic compounds. [1] In a silicon–oxygen bond, electrons are shared unequally between the two atoms , with oxygen taking the larger share due to its greater electronegativity .
