atoms 1) lattice combining -> regular repeating pattern of atoms resulting in the 3D structure. 2) ionic lattice > - regular repeating alternating pattern of positive and negative ions resulting in a 3D structure. 3) ionic bond- > (1m) electrostatic forces of attraction between two oppositely charged ions. (3m) Im + it is a bond formed between a metal and a non metal where the metal loses the electron while the nonmetal gains the electron. Iron (111) oxide Fest j2- IONIC LATTICE Fez03 - T 2 3( ↓ - - t - & lonic compounds do not conduct electricity when in solid state since the ions are in a fixed position. They do conduct electricity when in molten state since the ions are free to more.
