Ionic Bonding Flashcards
What is ionic bonding?
Transferring of electrons.
Atoms lose or gain electrons to from…
Charged particles.
What are the charged particles called?
Ions.
Why are electrons strongly attracted to one another?
Because of the attraction of opposite charges.
+ and -.
A shell with just one electron wants to…
Get rid of the electron.
Where are all the atoms located on the periodic table?
Left-hand side.
Name 3 atoms which only have one or two electrons in their outer shell
Sodium.
Potassium.
Calcium.
Why do electrons want to lose electrons out of their shells?
They will only have full outer shells left.
Atoms try to have the same electronic structure as…
A noble gas.
A nearly full shell wants…
An extra electron.
Group 6 and 7 have nearly…
Full outer shells.
When they gain and lose electrons the atom becomes an?
Ion.
When the atom loses an electron it becomes?
Positive ion.
When the atom gains an electron it becomes?
Negative ion.
What is the structure like in an ionic compound?
Regular lattice structure.
What are the lattices like in ionic compounds?
Giant ionic lattices.
Regular lattice arrangements are what?
Very strong electrostatic forces of attraction between oppositely charged ions, in all directions.
What is a single crystal of sodium chloride?
One giant ionic lattice.
Ionic compounds all have…
Similar properties.
What do Ionic compounds have?
High melting point.
High boiling points.
Easily dissolved.
What happens when ionic compounds melt?
Ions are free to move and they will carry electric currents.
How much energy does it take to over come the attraction?
Large amount.
What happens when an ion dissolves?
Ions separate and are free to move around in solution.
Carry electric currents.
