Unit 2 properties of matter

2.5 Have a basic knowledge of the periodic table, which includes being able to predict whether an element is a metal or a nonmetal, and what will be the probable charge of its ion.

  • As you go from left to right across the periodic table, the elements go from (metals / nonmetals) to (metals / nonmetals).

  • Where are the most active metals located?

  • Where are the most active nonmetals located?


Unit 2 properties of matter

  • Elements of Group 1 are called _______

  • Elements of Group 2 are called _______

  • Elements of Group 3-12 are called _______


Unit 2 properties of matter

  • Group 17 elements are called _______

  • The most active element in Group 17 is _____

  • Group 18 elements are called _______


Unit 2 properties of matter

  • The majority of elements in the periodic table are (metals / nonmetals).

  • Elements in the periodic table are arranged according to their _______

  • An element with both metallic and nonmetallic properties is called a _______


2 6 be able to write the correct name of an inorganic compound from its formula and vice versa

2.6 Be able to write the correct name of an inorganic compound from its formula and vice versa.

Type I: Binary Ionic

Writing Names from Formulas

1. Identifying the cation as a Group I metal , Group II metal, Aluminum, Zinc, or Silver

2. Identify the anion as a nonmetal

3. Name the cation (the metal) with its full name

4. Name the anion (the nonmetal) by changing the ending to -ide

Example: NaCl

cation: sodium & anion: chlorine

Name: sodium chloride


Unit 2 properties of matter

NaClBeO AlCl3

KBr CaF2Zn2O

MgI2Cs2S Ag3P


Unit 2 properties of matter

Writing Formulas from Names

1. Identify charge of cation (1+, 2+, 3+)

2. Identify charge of anion (1-, 2-, 3-)

3. Balance the charges

4. The charge of the cation becomes the subscript of the anion

5. The charge of the anion becomes the subscript of the cation

6. Reduce subscripts if necessary


Unit 2 properties of matter

Aluminum Sulfide Potassium Oxide

Sodium Nitride Barium Carbide

Zinc Chloride Potassium Iodide

Lithium Sulfide Silver Fluoride


Unit 2 properties of matter

Type I: Polyatomic

Writing Names from Formulas

1. Identifying the cation as a Group I metal , Group II metal, Aluminum, Zinc, or Silver

2. Identify the anion as a polyatomic ion

3. Name the cation (the metal) with its full name

4. Name the anion (the polyatomic) with its full name

Example: KOH

cation: potassium & anion: hydroxide

Name: potassium hydroxide


Unit 2 properties of matter

KCN LiSO3

FrClO2 NaOH

CsPO4 MgSiO3

CaCO3NH4Cl

BaC2O4


Unit 2 properties of matter

Writing Formulas from Names (polyatomics)

silver nitrate strontium chlorate

aluminum dichromate

magnesium sulfate barium cyanide

ammonium sulfate

calcium hydroxide zinc silicate


Unit 2 properties of matter

Type II: Transition Metals

Writing Names from Formulas

1. Identify the cation as a transition metal

2. Identify the anion

3. Identify the charge of the cation

4. Name the cation (the transition metal) with its full name and the charge of the ion in roman numerals

5a. Name the anion (the nonmetal) by changing the ending to –ide

5b. Name the anion (the polyatomic) with its full name

Example: CoBr2

Cation: cobat 2+ & anion: 2 bromine

Name: cobalt (II) bromide

CuI Co2(CO3)3

HgBr2CuI2

SnO Hg2Br2

CoCO3 SnO2

SnS


Unit 2 properties of matter

Writing Formulas from Names (transitional metals)

iron(II) oxide chromium(III) phosphate

iron(III) hydroxide iron(III) oxide

manganese (II) fluoride lead(IV) sulfite

chromium(II) phosphate

manganese (III) fluoride mercury(I) sulfide


Naming molecular compounds

Naming Molecular Compounds

Writing Names from Formulas

1. Both cation and anion are nonmetals

2. Use prefixes to indicate how many atoms are present

3. Name the first element: prefix with its full name

4. Name the second element: prefix element name and change the ending to -ide

5. Do not use “mono” when naming the first element

Example: CS2

Elements: carbon & 2 sulfur

Name: carbon disulfide


Unit 2 properties of matter

Prefixes:

1: ______ 2: ______ 3: ______ 4: ______ 5: ______

6: ______ 7: ______ 8: ______ 9: ______ 10: ______

CO PCl3N2O

CO2SO3P2O5

NO2SF6NF3


Unit 2 properties of matter

Writing Formulas from Names

1. Identify the elements

2. Identify prefixes for each element

3. Charges do not matter for molecular formulas!!

diphosphorousmonosulfidecarbonmonoxide

diphosphoroustrioxidesulfur tetrafluoride

nitrogen triiodide carbon tetrabromide

nitrogen monoxide phosphorous hexabromide

dichlorineheptoxide


Naming acids

Naming Acids

Binary Acids

Binary acids contain only two different elements. One of them is H+ and the other is an anion. To name them take the anion root word, put hydro in front of it and change the ending from ide to ic acid.

Examples:

HCl – hydrochloric acid

HI – hydroiodic acid


Unit 2 properties of matter

OxyacidsOxyacids are acids whose anions are polyatomic anions that contain oxygen. H+ is still the cation. These acids are named based on the nature of the anion as shown in the table below.

Examples:

HClO4 – perchloric acid

HClO3 – chloric acid

HClO2 – chlorous acid

HClO – hypochlorous acid


Unit 2 properties of matter

HF H3PO4 HNO3

HI HC2H3O2H2SO3

HBr H2CO3HCN


Unit 2 properties of matter

Writing Formulas from Names

1. Identify elements

2. Identify type of anion

3a. Hydro : there is no oxygen in the formula

3b. –ic acid : look for the polyatomic with –ate ending

3c. –ous acid: look for polyatomic with –ite ending


Unit 2 properties of matter

hydrobromic acid hydrocyanic acid

nitrous acid hydrofluoric acid

carbonic acid nitric acid
