FJ
Metals tend to form what kind of
ion?
Answer…
Cation
(they LOSE 1 or more electrons)
100
What happens after an atom’s
outermost energy level becomes
filled?
Answer…
It has a stable octet and is
unreactive
(it’s happy as a clam!)
200
What does the term
“electrically neutral” mean?
Answer…
The positive charges on the
cations and the negative charges
on the anions cancel each other
out in an ionic compound.
=
300
Which group in the periodic table
satisfy the octet rule without
forming compounds?
Answer…
The noble gases
(Group 18)
400
How many more electrons are
needed to form a stable ion in an
atom whose electron configuration
is 1s22s22p3?
Answer…
3
(There are 5 valence electrons and
the atom needs 8 to become a
stable ion, meaning it needs 3
more electrons)
500
True/False
Ionic compounds have low
boiling points?
Answer…
False
(The strength of the ionic bond
requires a lot of energy to break)
100
What is the energy released when
a salt is formed from its gaseous
ions called?
Answer…
Lattice Energy
200
How many sodium ions are
clustered around the chloride ions
in the NaCl crystal?
Answer…
6
300
Why do ionic compounds have
higher melting points than
molecular compounds?
Answer…
The ions in ionic compounds are
much more strongly attracted,
resulting in a stronger, ionic bond.
400
Why are ionic compounds brittle?
Answer…
The strong attractive forces in ionic
compounds holds the layers in
fixed positions. If the force
becomes too strong to withstand,
the crystal will fracture down a
cleavage plane.
500
What does the symbol HCO3
represent?
-
Answer…
A polyatomic ion
100
What is the formula for the compound
formed by barium ions, Ba2+, and
fluoride ions, F-?
Answer…
BaF2
(The barium ion has a 2+ charge
and the fluoride ion has a 1
charge, 2 fluoride ions are needed
to balance the charges)
200
Name the compound KNO3
Answer…
Potassium Nitrate
+
1
(Potassium forms a
ion and
nitrate is a polyatomic ion with a 1charge so they balance each other
out)
300
What is the formula for the
compound formed by the calcium
ion, Ca2+, and the hydroxide ion,
OH-?
Answer…
Ca(OH)2
(Calcium forms a 2+ ion and the
hydroxide ion is a polyatomic ion
with a charge of 1- so 2 of them
are needed to balance the
charges)
400
Name the compound CuCO3
(Be careful!)
Answer…
Copper (II) Carbonate
(The carbonate polyatomic ion has
a charge of 2-, so the charge on
the copper ion must be 2+ to
balance out the charges)
500
How is an ion different from its
parent atom?
Answer…
An ion has:
- a charge
- a different number of electrons;
- a different electron configuration;
- different chemical properties
than its parent atom.
100
Will a fluorine atom form an anion
or a cation?
Why?
Answer…
A fluorine atom will form an anion
because fluorine has 7 valence
electrons and really wants 1 more
to have an octet. By gaining 1
electron, fluorine will form an anion
with a 1- charge.
200
What do the 2+ and 3+ in the ions
Fe2+ and Fe3+ mean and how does
an Fe atom get these charges?
Answer…
The 2+ and 3+ indicate the
charges on the Fe cation. Iron is a
transition metal and loses either 2
or 3 electrons to form a cation with
either a 2+ or 3+ charge.
300
List 3 properties of ionic
compounds.
Answer…
1.
2.
3.
4.
5.
Solids at room temperature
Hard/Brittle
Strong
High melting/boiling points
Conduct electric current in
liquid state or when
dissolved in water
6. Non-conductors in solid
state
7. Fracture along a cleavage
plane
8. Not made of molecules 400
Why is lattice energy the key to
forming an ionic bond?
Answer…
Enough energy is released to
make the whole process
spontaneous. Without the big
release of lattice energy, the
overall process would not happen
spontaneously.
500
“They’re here”
Name the movie
Answer…
Carol Anne Freeling,
played by Heather O’Rourke in
Poltergeist
100
“Houston, we have a problem.”
Answer…
Jim Lovell, played by Tom Hanks
in Apollo 13
200
“Here’s Johnny!”
Name the movie
Answer…
Jack Torrance, played by Jack
Nicholson in The Shining
300
“Nobody puts ‘Baby’ in a corner”
Name the movie
Answer…
Johnny Castle, played by Patrick
Swayze in Dirty Dancing
400
“You’re gonna need a bigger boat,
right?”
Name the movie
Answer…
Martin Brody, played by Roy
Scheider in Jaws.
