600

Non-Metals will form what type of ions, having which charge? 

Anions; Negative

Ionic Bonds

100

An ionic bond is formed between which two types of ions?

Cations and anions

200

Ionic compounds are electrically _______.

Neutral

300

A common name for most ionic compounds is: 

Salts

400

Most ionic compounds are which state at room temperature? 

Solid

500

When ionic compounds are melted or dissolved, they have the ability to do what? 

Conduct electricity

600

To calculate the overall charge of an ion, what do we do with the subscript and the atom's original charge? (Ex: How would we calculate the charge of Calcium in Na₂O)

Multiply the subscript and the original charge 

Naming/Writing Ionic Compounds

100

How many elements are in a binary compound? 

Two

200

What is the difference between a compound and a polyatomic ion? 

Polyatomic ions have a charge

300

What is incorrect about the following written name: 

Copper Oxide

Copper (II) Oxide

400

What changes about the name of the anion in an ionic compound? 

Has the suffix -ide

500

What is the proper name for the following compound: 

K3PO4

Potassium Phosphate

600

Which elements will require Roman Numerals next to them when writing the names?  What does the Roman Numeral tell us about the ion? 

Transition Metals; Its charge

Name the Charge

100

Charge of Potassium in K3PO4

3+

200

Charge of lead in: Lead (IV) Chloride

4+ 

300

What subscript would need to be written by Chlorine when writing the formula for Lead (IV) Chloride? 

4

400

Charge of Aluminum

3+

500

Explain why Lithium forms a 1+ ion.

Lithium contains 1 valence electron, which is easily lost when forming compounds. There is one more proton than electrons in this ion, and therefore a net charge of 1+

600

Charge of Copper in CuO

2+ 

Random Chemistry

100

What number tells us the number of protons in an element? 

Atomic Number

200

If an element is in row 4, how many energy levels will it have? 

4

300

You mix two chemicals together.  There is no bubbling, no color change, no precipitate formed, but the test tube gets colder.  Did a chemical reaction occur?
