Unformatted text preview: Atoms will try to gain or lose electrons in order to fill their outer shell or valence shell. The number of electrons to be gained or lost is called the valence . STRONG BONDS::: Bonds which are the result of very strong electrical attraction, where electrons are lost or gained are called IONIC BONDS . Bonds which are the result of electrical attractions which are not so strong, where the electrons are shared are COVALENT BONDS . POLAR COVALENT BONDS Can these bonds can be considered to grade from one to another? What determines the number and type of bond? Electronegativity Weak Bonds: A bond which is the result of very weak electrical attractions between atoms bearing partial electrical charges are HYDROGEN BONDS . One atom involved must be Hydrogen...
