Ions and Ionic Compounds
Mr. Ted Torretti
1
Metals
tend to release electrons during chemical reactions. This process is referred to as (1 point)
They have too many valence electrons.
2
Non-metals
on the other hand need more electrons and will tend to
accept
electrons during a chemical reaction. This process is referred to as (1 point)
They have too few valence electrons and want to have an electronic makeup similar to a noble gas.
3
The
oxidation state
for an element tells you (1 point)
4
A
monatomic ion
would be one that is composed of (1 point)
5
A
polyatomic
ion is composed of (1 point)
Remember, you need not memorize the list of polyatomic ions, it will always be available to refer to.
6
Ions formed by
halogens
typically have a charge of (1 point)
Want to gain an electron.
7
Ions formed by
alkaline earth metals
typically have what charge? (1 point)
They want to lose two electrons.
8
What is the
name
of this ion?
Ga
3+
(1 point)
Named after the element.
9
What is the
name
of this ion?
As
3-
(1 point)
Remember, use the root of the name of the element, then add a new suffix (-ide).
10
What is the
name
of this ion?
Ni
3+
(1 point)
Watch the transitional metals, they tend to have more than one oxidation state. use the Roman Numerals to specify the state.
11
What is the
name
of this ion?
At
1-
(1 point)
12
What is the correct
formula
for
cupric ion
? (1 point)
13
What is the correct
formula
for
phosphide
? (1 point)
Remember, the oxidation state for the monatomic anions are determined by finding the group they are in and referring to your everyday table, where we listed the group values.
14
What is the correct
formula
for
plumbous
ion? (1 point)
15
What is the
formula
for
sodium sulfide
? (1 point)
Remember, to come up with the correct formula for an ionic compound, the charges on the cation and the anion must balance out.
16
What is the
formula
for
platinum (IV) oxide
? (1 point)
17
What is the
formula
for
strontium phosphide
? (1 point)
18
What is the
formula
for
ammonium carbonate
? (1 point)
19
What is the
formula
for
lithium thiosulfate
? (1 point)
20
What is the
formula
for
manganese (III) hydroxide
? (1 point)
21
What is the
name
for

(1 point)
In naming ionic compounds, simply name the cation and then name the anion that the compound is composed.
