Ionic bonds are sometimes called electrovalent bonds. ... Positive ions are attracted to the lone pairs on water molecules and co-ordinate (dative covalent) bonds may form. Water molecules form hydrogen bonds with negative ions. ... CO-VALENT Molecular BONDING Covalent bond: the electrostatic bonds between the shared pairs of electrons and the neighbouring nucleus. (+) † (-) † (+) Cl : Cl As well as achieving noble gas structures by transferring electrons from one atom to another as in ionic bonding, it is also possible for atoms to reach these stable structures by sharing ele...

During the process of protein synthesis for the normal and mutated prion, special bonds known as peptide bonds form a polypeptide chain. ... The helical structure of a polypeptide results from hydrogen bonds between elements of peptide bonds that are distributed along the backbone of the chain. ... They are stabilized by hydrogen bonds between the elements of the peptide linkage. ... The intermolecular interactions are a result of hydrogen, ionic and covalent interactions. ...

A key property of a conductive polymer is the presence of conjugated double bonds along the backbone of the polymer. In conjugation, the bonds between the carbon atoms are alternately single and double. ... Diamond, which contains only bonds, is an insulator and its high symmetry gives it isotropic properties. ...
