This lab was done to look at the properties of covalent and ionic compound. ... After the experiment is conducted the compound is classified as either covalent or ionic. ... Covalent bonds are formed when elements share electrons, and ionic bonds form only from a metal and a nonmetal. Ionic bonds tend to have high melting points, be nonconductors, and be very brittle. Covalent bonds usually have the opposite characteristics of ionic bonds (low melting point, good conductor, etcetera). ...

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...

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. ...
