Ionic and Covalent Bonding

Ionic bond is the…

• chemical bond involving SHARING of electrons between two nonmetal atoms; electronegativity difference between elements typically LESS than 1.7

• Chemical bond involving the TRANSFER of electrons between a metal and nonmetal atom (metals lose, nonmetals gain); electronegativity difference between elements typically GREATER than 1.7

• bonding of two ions with the SAME charge. Typical electronegativity difference between elements LESS than 1.7

• Chemical bond involving the TRANSFER of electrons between a metal and nonmetal atom (metals gain, nonmetals lose); electronegativity difference between elements typically LESS than 1.7
