BONDINGS
IONIC BOND
two elements exchanging one or more electrons to complete their outer shell
two ions produced have an electrostatic interaction forming a LATTICE
molecules cannot be built as a lattice is produced
when the electronegativity difference is higher than 1.7 and lower than 4
COVALENT BOND
two elements close in the periodic table which cannot gain or lose electrons
therefore they share electrons and join each other making this new structure
polar covalent
when the electronegativity difference is higher than 0.4 but lower than 1.7
non-polar covalent
when electronegativity difference is between 0.0 and 0.4
METALLIC BOND
bond between metal positively charged atoms in which the free elctrons are shared
ELECTRONEGATIVITY DIFFERENCE
to predict the bond type
the higher the electronegativity, the higher the ability to attract electrons
between two elements, the one with higher electronegativity, is followed by a (-) sign as it gives, and therefore loses, one or more electrons to the other element
