Ionic bonding

Square box stuffChemical ideas 3.1 page 34

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

Magnesium Fluoride
