Monday, January 25, 2010 Chemical bonds Attraction between atoms – each atom has a full outermost shell at least part of the time. Faciliates a complete outermost cell. Different types of bonds – ionic, covalent, metallic, hydrogen, polar, nonpolar, van der waals Strong bonds- covalent > ionic. Weak bonds- the rest Covalent bonds- sharing equally / unequally. Nonpolar = equal. Polar = inequal + partial charges.
