The mass # tells the ______

it contains only two atoms

(H₂, N₂, HCl, CO, O₂)

what is the definition of a polyatomic molecule?

it contains more than two atoms

(O₃, H₂O, NH₃, CH₄)

What are the 2 categories of an ion?

What are their individual definitions?

Cation and Anion

Cation- is an ion with a positive charge; metal, and loses electrons to form cations

Anion- is an ion with a negative charge; non-metal atoms gain electrons to form anions

What is a monatomic ion?

What is a polyatomic ion?

Mono- (one) contains only one atom

Na⁺,Cl^-, Ca²⁺, O^2-, Al^3-

Poly- (many) contains more than one atom

 OH^-, CN^-, NH₄⁺, NO₃^-

Prontons- 13

Electrons- 10

What does the molecular formula show?

It shows the exact number of atoms of each element in the smallest unit of a substance.

It is a compound consisting of a combination of cations and anions.

The formula is always the same as the empirical formula.

The sum of the charges on the cation(s) and anion(s) in each formula must equal zero.

What is the rule for naming Ionic Compounds whose cation forms only one charge?

Name NaCl

Name Mg₃(PO₄)₂

Lithium Sulfide

1.) Write the name of the cation first

2.) Write the charge on the cation as a Roman Numeral

3.) Write the name of the anion

Name - Fe₂Cl

Name - Sn₂O

What is the difference between ionic and molecular compounds?

Ionic compounds have metal in the compound

Molecular compounds have no metal in the compound.

1.) Name the first element and add -ide to the stem of the name of the second element

2.) Indicate the number of each element by the use of greek prefixes.

Name - N₂O₄

What makes an acid?

How do you name an acid?

It is a molecular compound that yields hydrogen ions, H+, when dissolved in water.

If (aq)"meaning aqueous solution" is at the end of the name, add Hydro- and Acid

HCl(aq) - Hydrochloric Acid

Name - H₂S

It is an acid that contains hydrogen, oxygen, and another element.

What happens if the suffix of the anion is -ate?       -ite?

If it is -ate, it becomes -ic.

If it is -ite, it becomes -ous.

Nitric Acid

Name - HNO₃

Name - H₂SO₃

Phosphuric Acid

Name - HClO₃
