METALLIC COMPOUNDS Strong bonding generally results in: Dense, strong materials with high melting and boiling points. Metals are good conductors of electricity and heat because these 'free' electrons carry the charge of an electric current when a potential difference (voltage!) is applied across a piece of metal. Metals typically have a silvery surface (but this may be easily tarnished by oxidation in air and water), are malleable, and ductile.

IONIC BONDING The electrons (e - ) are completely transferred from the metal to non- metal in the formation of ionic bonds. Note the electron affinities of metals compared to non-metals as well as the ionization energies. This results in the formations of positive metal ions ( cations ) and negative non-metal ions ( anions ).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
