- Ionic bonding
- Transferring electrons
- In ionic bonding, atoms lose or gain electrons to form ions.
- Ions can have a postive (+) or negative (-) charge.
- Oppositely charged ions are attracted to each other to form ionic bonds
- A shell with just one or two electrons wants to lose them...
- Atoms with just one or two electrons in their outer shell (highest energy level) want to lose these.
- then they will have a full outer shell. This means they will have the same electronic structure as a noble gas
- A Nearly full shell wants to gain electrons...
- Atoms with a nearly full outer shell want to gain an extra one or two electrons to fill the shell up.
- So they take an electron (or two) from an atom that want to lose one (or two).
- exmaple
- sodium and chloride react together to make sodium chloride.
