Nomenclature

Question 0

Characteristics of Anions

Answer 0

• Nonmetals form anions
• Named as root of elemental name, ending in -ide
• Charge based on periodic table

Question 1

How do you name ionic compounds?

Answer 1

Write the cations, then the anions

Question 2

Characteristics of Cations?

Answer 2

• Metals form cations
• Named as elemental name
• Charge based off periodic table

Question 3

Which metals cannot form multiple cations?

Answer 3

Groups 1, 2, 11, 12, 13

Question 4

With metals that can form multiple cations, what must be done after the name in the formula?

Answer 4

Write the charge number in parenthesis

Question 5

Which rows are anions that end in -ate

Answer 5

2nd row - 3O’s

3rd row - 4O’s

Question 6

Characteristics of Hydrates

Answer 6

Compounds with water molecules trapped in their crystals

Name ionic compound first, then a prefix for the number of waters, followed by -hydrate

Question 7

Prefix for number of ions

Answer 7

1- mono    6- hexa
2- di         7- hepta
3- tri         8- octa
4- tetra    9- nona
5- penta 10- deca

Question 8

What to do with covalent compounds?

Answer 8

Name the 1st nonmetal as element name, using prefix if more than 1 atom
Name the 2nd nonmetal with –ide, always use a prefix

Question 9

Rules to naming acids

Answer 9

Arrhenius Acid – A compound that loses hydrogen ions in solution
Arrhenius Base – A compound that loses hydroxide ions in solution
Anion in acid ends in –ide
   hydro–root–ic acid
Anion in acid ends in –ate
   root–ic acid
Anion in acid ends in –ite
   root–ous acid
