Polyatomic Ion List

Front 1

Ammonium

Back 1

NH4+

Hint 1

2 elements, Positive!!!

Front 2

Acetate

Back 2

C2 H3 O2 -

Hint 2

These elements "Hate" each other because there are SO MANY. Also, what is the 2ND letter? *major hint*

Front 3

Cyanide

Back 3

CN ^-

Hint 3

Two letters with the y reaching down to pull up a negative....

Front 4

Carbonate

Back 4

CO3 ^-2

Hint 4

The first word is "car" which starts with a __ and has ___ letters in it. ___ letters after that is the letter O. List both letters first. List numbers (in same order) second.

Front 5

Chlorate

Back 5

ClO3 -

Hint 5

Chlorine duh. And another letter... And 2 numbers.

Front 6

Chlorite

Back 6

ClO2 ^-

Hint 6

2 Elements , 1 Number

Front 7

Chromate

Back 7

CrO4 ^-2

Hint 7

O is ___ spaces from beginning. And they're "mates" so there must be ___.

Front 8

Dichromate

Back 8

Cr2 O7 ^-2

Hint 8

Double Cr. O is almost doubled. Just subtract one. They're mates.

Front 9

Hydrogen Carbonate

Back 9

HCO3 ^-

Hint 9

Think Acetate but flip the letters around. How many letters are in the formula? That's your number and then the usual.

Front 10

Hydroxide

Back 10

OH ^-

Hint 10

Hy - drox - ide Simple!!!

Front 11

Hypochlorite

Back 11

ClO ^-

Hint 11

This one is super easy. Nothing special. Choose the obvious.

Front 12

Nitrate

Back 12

NO3 ^-

Hint 12

Okay the numbers are just like chlorate and chlorine I think.

Front 13

Nitrite

Back 13

NO2 ^-

Hint 13

Numbers just like chlorate and chlorine.

Front 14

Perchlorate

Back 14

ClO4 ^-

Hint 14

It's like chlorate, just slightly larger.

Front 15

Permanganate

Back 15

MnO4 ^-

Hint 15

Okay 3 elements plus corner of 1 is....

Front 16

Phosphate

Back 16

PO4 ^-3

Hint 16

2 Elements, 2 Numbers. _ _ 4 ^___

Front 17

Phosphite

Back 17

PO3 ^-3

Hint 17

There's how many letters in Pho?

Front 18

Sulfate

Back 18

SO3 ^-2

Hint 18

Same as chlorate and chlorite.

Front 19

All the ions have oxygen EXCEPT....?

Back 19

Ammonium: NH4 ^+1

Cyanide: CN ^-1

Hint 19

Don't and in "-ate" or "-ide"

Front 20

Which means it's larger, "-ate" or "-ite"

Back 20

"-ate" because the more things there are the more they HATE each other.... But not really.

Hint 20

"Hate"
