Ionic Bonding
- Ionic Bonding –
Transferring electrons
- In Ionic Bonding, atoms lose or gain electrons to form charged
particles (called ions) which are strongly attracted to one another
(because of the opposite changes + and -)
- A shell with just one electron is well keen to get rid of it
extra one electron to complete it shell
- Become a positive change
(E.g. Na+)
- Become a positive change
(E.g. Na+)
- A nearly full shell is well keen to get that
extra electron from another atom that has
an extra electron the it ‘wants’ to get rid
of, so it can have an complete shell
- Become a
Negative change
- Become a
Negative change
- A shell with just one electron is well keen to get rid of it
extra one electron to complete it shell
- In Ionic Bonding, atoms lose or gain electrons to form charged
particles (called ions) which are strongly attracted to one another
(because of the opposite changes + and -)
- Ionic compound has a
regular lattice structure
- Ionic compound always
have giant ionic lattices
- Ions form a closely packed
regular lattice arrangement
- Electrostatic forces of attraction
between oppositely charge ions, in all
directions.
- Ionic compound always
have giant ionic lattices
- Ionic compounds all
have similar properties
- They all have:
- High melting point
- High boiling point due to strong
attraction between the ions
- Ions are free to move
- Carry electric current
- Dissolve easily in water
- High melting point
- They all have:
