Polyatomic Ions(correctly answered)Tips for Learning the Ions 
"FROM THE TABLE" 
These are ions that can be organized into 2 groups. 
1. Their place of the periodic table suggests the charge on the ion, since the neutral atom gains or loses a predictable number of electrons in order to obtain a noble gas configuration. 
2. Notice that cations keep their name (sodium ion) while anions have an "-ide" suffix (chloride ion) 
3. Metals that can form more than one ion will have their positive char...

Polyatomic Ions graded A+ already passed
Polyatomic Ions graded A+ already passedA polyatomic ion is a charged particle which has two or more atoms held together by covalent (sharing of pairs of electrons) bonds 
Some rules: 
1. Ions that end in ate have oxygen in them. 
2. Elements in the same family make similar ions. So for example if you know chlorate, you also know bromate and iodate too (BrO3-, and IO3-). There are some exceptions. Nitrate is not like phosphate even though nitrogen and phosphorus are in the same group. However ar...
