Formation Of Ions And Ionic Bonding Flashcards
1
Q
Stable atoms
A
When an atom has a full outer shell of electrons, this means they are very unreactive.
Elements usually react in order to gain or lose electrons to get a full outer shell of electrons
2
Q
Forming ions
A
When an atom has lost or gained electrons it becomes an ion
A negative ion (gained electrons) = anion
A positive ion (lost electrons) = cation
3
Q
What are most ionic compounds between?
A
A metal and a non-metal
4
Q
How does ionic bonding occur?
A
When metals react they lose outer shell electrons to leave a full electron shell
When non-metals react witha metal they gain electrons to achieve a full electron shell
