- Ionic Bonding
- Transferring electrons
- Transfer of electrons allows atoms to become ions
- Ions are charged atoms
- Losing electrons makes a +ion
- Gaining electrons makes a - ion
- +ion and - ion attract and bond
- Losing electrons makes a +ion
- +ion and - ion attract and bond
- Transfer of electrons allows atoms to become ions
- Outer shells
- Right side of the periodic table (Groups 6/7)
- They nearly have a full outer shell, 6/7 electrons so they're keen to gain electrons.
- eg. O, Cl, S
- Left side of the periodic table (Groups 1/2)
- They only have 1/2 electrons on their outer shell so they're keen to give away electrons
- eg. Na, K, Ca
- Right side of the periodic table (Groups 6/7)
- Ionic compound structure
- Giant ionic lattice structure
- Closely packed
- Regular Lattice arrangement
- These features of the structure cause very strong electrostatic attraction in all directions between opposite charged ions
- Cuboid Shape
- Closely packed
- These features of the structure cause very strong electrostatic attraction in all directions between opposite charged ions
- Cuboid Shape
- Giant ionic lattice structure
- Ionic compound properties
- High melting and boiling points due to strong attraction in all directions
- Dissolve easily in water
- When dissolved or molten, ionic compounds carry electric current as their ions are free to move.
- Takes a large amount of energy to melt due to the strong electrostatic attractions
- When dissolved or molten, ionic compounds carry electric current as their ions are free to move.
- Takes a large amount of energy to melt due to the strong electrostatic attractions
- Brittle when crushed because the arrangement becomes irregular so the ions with same charge repel.
- Transferring electrons
