Chapter 2: Atoms, Ions, and Molecules Flashcards
What is the type 1 binary ionic?
The metal cation has a fixed charged. This means that there is 1 specific ion chrage that the metal can have
How do you name a simple compund that is a binary type 1?
First you write the name of the metal cation
Then anion name= (stem name) + “ide”
Name the elements that only have 1 possible cation charge
All group 1A metals (M^1+) All group 2A metals (M^2+) Al (Al^3+) Ga (Ga^3+) Ag (Ag^+) Zn (Zn^2+)
In a binary ionic ccompound what groups are associated?
Metal and Non-metal
What would happen if you had a metal cation with variable charge?
We will be dealing with a type 2 binary ionic compound
What groups of metal have varable charge?
Transition metals
How do you specify a cation if it has variable chrage?
You would need to use Roman numeral for the charge
How do you name a simple compound that is a binary type 2?
It’s the same as naming a simple compound for binary type 1
How do you know when to use binary covalent?
To know that it is a covalent the elements are on the right side of the periodic table
They would be both non-metals
In a binary covalent, what is a rule that you must follow?
You can not use “mono” for the first element
What are polyatomic ions?
Compounds with 3 or more atoms
What do we do if we have a situation where our compound contains a polyatomic ion, but it’s not the anion?
We would name this by writing the name of the cation first
For the anion, we would take the element stem and attach “ide” suffix at the end
When naming an acid how do you define it?
Define an acid as being any compound which as H+as the cation
What is the general naming formula with acids that don’t contain oxygen?
Hydro–(anion stem)– ic acid
If the anion ends with –ate what is the general naming formula?
(polyatomic stem–) –ic acid
If the anion ends with –ite what is the general naming formula?
(polyatomic stem–) –ous acid
