ionic bonding Chemistry grade 10 Senior High School.ppt

1. Ionic bonding

2. Ionic bonding
Square box stuff
Chemical ideas 3.1 page 34

3. Use simple dot cross
diagrams to describe how
atoms bond through ionic
bonding.
Learning outcomes

4. Compounds contain a metal and a non-metal
Metals form + ions(and hydrogen) Non-
metals form negative ions
Ionic bonding

5. Electron configuration of metal ions
Na (Z = 11) 2,8,1
S (Z= 16) 2,8,6
Na+
2,8
S2-
2, 8
Do Q1 Page 40 a – e only

6. Conducts electricity when MOLTEN
or in SOLUTION(aq)
High melting point and boiling point
hard solids
Properties of Ionic compounds
Form crystalline structures

7. Non directional bonds The
strength of the bond equal
in all directions
Forces between the ions
are very strong

8. NaCl is the formula unit
GIANT LATTICE

13. Magnesium Fluoride

14. Now do question 3and
