How are Cations are named
after their parent ion, with ion at the end.
How are anions named
with an ide ending
What's the net charge of a chemical compound
must be a net 0 charge
What are binary ionic compounds composed of
a nonmental and a metal
How do you list a name of a compound?
nonmetal (modified to identify the stem),
+and -ide ending.
What do the roman numerals placed in parentheses immediately following the name of a metal mean
the charge on a cation
how do you modify the end of a metal depending on it's charge?
-ide= nonmetal name ending
Binary compounds containing 2 nonmetals: molecular or ionic
molecular, because they have not lost or gained an electron

Naming acids with non-mental
hydro- in front of the nonmetal.
-ic end for the nonmetal.
What's a polyatomic ion
ion with 2 or more elements
What do polyatomic ions consist mostly of
1+ cations with negative polyatomic ion.
Na2CO3 (Na2=cation; CO3=negative polyatomic ion).
How do you name a compound containing a polyatomic ion
cation first, then anion.
why do some anions end in -ate
they contain more oxyten than those ending in -ite.
What does per- denote?
Short for hyper, denotes an anion with more oxygen than the -ate ending form.
anion with less oxygen than -ite form
List 3 common positively charges polyatomic ions
