Ionic Bonding Flashcards
What is Ionic Bonding?
Ionic Bonding is when atoms LOSE or GAIN electrons to form charged particles ( IONS ) whih are then strongly attracted to one another ( attraction of opposite charges )
A shell with just one electron is …
Keen to get rid of the outer shell because then they’ll have full outer shells left, which is how they like to end up. Ions jump at the chance to bond with the opposite charge
>groups on the left hand side of the periodic table
A shell with a nearly full outer shell is…
Keen to gain an extra electron to fill the shell up. When they do they become ions.
>groups on the right hand side of the periodic table
Ionic Bonding looks like
[o]- [o]+
When ionic bonding takes place.. The ion becomes + which is..
When the atom gives an electron
When ionic bonding takes place.. The ion becomes - which is..
When the atom gains (gets) an electron
Ionic Compounds have a … structure.
This means that…
> Arrangement?
> Attraction?
A Regular Lattice Shape
This means that…
> Ions are packed in a regular lattice arrangement
>Strong ELECTROSTATIC force of attraction between oppositely charged ions.
Ionic Compounds all have … Properties.
Similar.
Ionic Compounds
>Melting and boiling points?
> HIGH melting and boiling points, due to the strong attraction between the ions.
Ionic Compounds
>Energy?
> They need large amounts of energy to overcome this attraction.
Ionic Compounds
>Melt?
> When they melt, ions are free to move and they’ll carry the electrostatic current.
Ionic Compounds
>Dissolve?
> Dissolve easily in water. The ions seperate and all are free to move in the solution so that they’ll carry electric current.
