Chromate ion
10
Q
Chromate ion
A
mate thats messed up
Think its just adding 1 more to the oxygen adn 1 more to the charge than you would expect
11
Q
A
Cyanide ion
12
Q
Cyanide ion
A
13
Q
A
Dichromate ion
Think lucky 7, and di = 2 twice
14
Q
Dichromate ion
A
15
Q
A
Hydrogen Carbonate ion
16
Q
Hydrogen carbonate ion
A
17
Q
A
Hydrogen sulfate ion
18
Q
Hydrogen sulfate ion
A
the charge makes sense, on a normal sulfate ion you have a 2- charge, so hydrogen just took 1 away
19
Q
A
Hydroxide ion
20
Q
Hydroxide ion
A
21
Q
A
hypochlorite ion
22
Q
Hypochlorite ion

Nitrate ion
24
Q
Nitrate ion
A
25
Nitrite ion
26
Nitrite ion
27
Perchlorate ion
28
Perchlorate ion
29
Permanganate ion
30
Permanganate ion
31
Phosphate ion
32
Phosphate ion
33
Sulfate ion
34
Sulfate ion
35
remember, sulfur is one shifted up on the oxygen and the charge from what you would expect
Sulfite ion
36
Sulfite ion
remember, sulfur has 1 more of everything than you would expect
37
Ammonium ion (notice this is an cation)
38
Ammonium ion
39
NOTE: The reason that the polyatomic atoms are almost all anions because oxygen is so electronegative.
40
Polyatomic ions are essentially covalently bonded atoms (molecules) w/ a charge attached to them (mostly negative because oxygen is electronegative)
