Use simple dot cross diagrams to describe how atoms bond through ionic bonding.
Learning outcomes
Compounds contain a metal and a non-metal
Metals form + ions(and hydrogen) Non-metals form negative ions
Ionic bonding
Electron configuration of metal ions
Na (Z = 11) 2,8,1
S (Z= 16) 2,8,6
Na+ 2,8
S2- 2, 8Do Q1 Page 40 a – e only
Conducts electricity when MOLTEN or in SOLUTION(aq)
High melting point and boiling point hard solids
Properties of Ionic compounds
Form crystalline structures
Non directional bonds The strength of the bond equal in all directions
Forces between the ions are very strong
NaCl is the formula unit
GIANT LATTICE
