Ionic Flashcards
Why are electrons and ions strongly attracted to each other?
Opposite charges , + and - attract
Which side of the periodic table like to get rid of one or two electrons in ionic bonding?
The left, then they’ll only have full shells left
Some atoms like to get rid of an electron because…
Then they’ll have only have full shells left, giving them the electronic structure of a noble gas
Ions tend to leap at …
The first passing ion with an opposite charge
What is an ion?
Atoms which lose or gain electrons to form charged particles
In ionic bonding in order to form charged particles ( ions ) atoms …
Lose or gain electrons
Which groups have outer shells that are nearly full?
6 and 7, who are keen to get extra electrons to fill up their outer shells.
What kind of structure do ionic compounds have?
Always giant ionic lattices, in a closely packed regular lattice arrangement
In ionic compounds what forces are present?
Very strong electrostatic forces of attraction between oppositely charged ions in all directions
Ionic compounds have high melting and boiling points due to …
Strong attraction between the ions. It takes a large amount of energy to overcome the attraction
What happens when the ionic compounds melt?
Ions are free to move , carrying electric currents
What happens in water to ionic compounds?
The ions separate and are all free to to move easily in the solution, carrying a electric current
Which groups are most likely to form ions?
1 and 2 ( left )
6 and 7 ( right )
What electronic structure do ions have ?
That of a noble gas
Atoms that have lost or gained electron (s) are known as what ?
Ions
