Activity 3: BONDING BY TRANSFER OF ELECTRONS
Direction: Write the Lewis Symbol of the selected metallic and non-metallic elements. Take note of
the electronegativity values of both elements. Subtract the Electronegativity value of the metallic
element from non-metallic element.
Take note: If the difference is greater than 1.9, complete transfer of electrons is possible.
