|
P 2+3 group 1-4
|
Have a giant metallic structure
With strong forces between positive ions and negative delocalised electrons. They are bonded through metallic bonding. |
Structure, force, binding

|
|
P2,3 group 4-5
|
They have a giant covalent structure with covalent bonding that results into having strong forces between the atoms.
|
Structure, bonding, force

|
P2,3 group 5-0
|
A simple molecular structure with the bonding of Van Der Waals' forces. They have a weak force between each molecule.
|
Structure. Bond. Force.

|
|
Group 1-4 m+b points?
|
They increase across the periods from group 1-4 due to giant metallic structure and the metallic bonding.
|
Increase
|
|
|
Group 4-5 m+b points
|
Decrease sharply because of covalent bonding and giant covalent structure.
|
Decrease
|
|
|
Group 5-0 m+b points
|
Low boiling and melting points because of the simple molecular structure and weak forces of van Der waals
|
Low
