What is an anion?
A negatively charges ion
True or false?
Crisscross your charges for all types of naming
False

When do you need to incorporate diatomics in writing chemical equations?
ONLY when they are a single atom (by themselves)
How do you know what element in a compound is replaced in a single displacement reaction?
The single element will replace the element in a compound that plays the same role.
Ex. Anion replaces and anion, cation replaces a cation
