M-1 Naming Covalent and Ionic Bonds

Given the periodic table, provide the electron charges.

Given the periodic table, find the transition and post transition metals.

Given the periodic table, find the metals.

Given the periodic table, find the non-metals.

Given the periodic table, find the metalloids.

What consists of a binary COVALENT compound?

Two NON-metals

• elements share electrons to bond

• Example: C and Cl{4}

What are the rules to naming binary covalent compounds?

1. Prefixes indicate subscript!

2. Change ending of the 2nd element to -ide

What is the prefix for the number of atoms given? *Covalent bonds only

# of atoms: Prefix name?

1

2

3

4

5

6

7

8

9

10

What is the weird exception to the naming of covalent binary compounds?

The first element never receives “mono”

What is an ionic compound?

ONE metal and ONE NON-metal

For ionic bonds (ONE metal + ONE NON-metal), the charges need to end up being ________

Neutral.

C + A = net charge of zero.

Cation vs Anion

Cation: positive charge, loses electrons, metals

Anions: negative charge, gains electrons, NON-metals

What are the rules for binary ionic compounds?

Cation, Anion [order matters]

Metal, nonmetal

Cation + anion-ide ←

*no transition, post transition, nor Polyatomics here*

What is the correct order of ionic compounds?

Cation, Anion [order matters]

Metal, nonmetal

The net charge of ionic compounds must be _____

Zero

Mostly all polyatomics are ___________ with the exception of __________.

Nonmetals

Ammonium (metal)

Can you split up polyatomics?

NO!

What are the rules for a binary ionic compounds must with a polyatomic?

Cation + anion [polyatomic]

*notice that names do NOT change with polyatomics!!

• Roman numerals represent __________

Roman Numerals represent the charges of the cations (metals)

• specifically transition or post transition metals

What are the rules of binary ionic compounds with Roman numerals?

Cation (__roman numeral__), anion-ide

What are the rules of binary ionic compounds with (post) transitions and polyatomics?

Cation (…Roman numeral…) polyatomic ion (no name change)

*tricks!

• ends in -ide → ____________

• ends in -ate → ____________

-ide: an element in the periodic table, not a polyatomic (cyanide exception)

-ate: a polyatomic

T/F your Roman numeral always represents a positive charge.

True because the Roman numeral is the charge of one element of the cation.

True or False.

Ammonium is considered a “metal”

True. Ammonium has a +1 charge.

What are the transition metal exceptions? List their charges as well.

What is the name?

What is the symbol for gold (I) oxide?

What is the name?

Calcium Chloride

What is the name?

Dinitrogen tetroxide

What is the name?

Iron (III) iodide

What is the formula?

Nickel (III) Sulfate

What is the formula?

Barium hydroxide

What is the name?

Copper (II) phosphate
