Naming chemical compounds

Question 1

What is the first rule for naming ionic compunds?

Answer 1

the symbol for a cation is always written first followed by the symbol got the anion

Question 2

What is the second rule for naming ionic compunds?

Answer 2

Subscripts represent the number of the ions of each element in an ionic compound

Question 3

What is the third rule for naming ionic compunds?

Answer 3

The total charge must equal 0

Question 4

What are the seven diatomic molecules. (Have No Fear Of Ice Cold Bear)

Answer 4

Hydrogen-H
Nitrogen-N
Florine-F
Oxygen-O
Iodine-I
Chlorine-Cl
Bromine-Br

Question 5

What is a diatomic molecule

Answer 5

A molecule that has two of the same element bonded together

Question 6

What is a monoatomic ion

Answer 6

One atom ions which oxidation no. or state is the charge of the ion

Question 7

What is a subscip

Answer 7

Represents the no. of ions of each element in a compound(is found behind the symbol of the elemnt)

Question 8

Can you change the subscrip of a polyatomic ion?

Answer 8

No, polyatomic ions are one unit and they can not be split up. If there is more then one polyatmic ion needed in an equation you put the subscript outside a parenthesis.

Question 9

What is an oxyanion

Answer 9

Oxyanion is a polyatomic ion composed of one or more oxygen atoms and another element(Usually a non metal)

Question 10

What are the steps to naming ionic compounds?

Answer 10

1. identify cation and anions

2.Does the cation have only one oxydation no.?

3. Yes- Write cation followed by anion
   No- Write cation followed by a roman numeral that represents the charge then write the anion.

Question 11

What is the first rule for naming covalent compounds?

Answer 11

The first element is always named first

Question 12

What is the second rule for naming covalent compounds?

Answer 12

The second element will always end in the prefix -ide

Question 13

What is the third rule for naming covalent compounds?

Answer 13

If there are two anions in a compound then the one with a lower electronegativity goes first

Question 14

What is the fourth rule for naming covalent compounds?

Answer 14

Prefixes are used to indicate no. of atoms in each element. (mono prefix is forgotten in the first element listed.

Question 15

What are the prefixes used in covalent compounds

Answer 15

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

Question 16

What do acids contain

Answer 16

Hydrogen + at least 1 other element

Question 17

What is an oxyacid

Answer 17

An acid containing both a hydrogen atom and an oxyanion

Question 18

What is the first rule in naming acids

Answer 18

The first word has the prefix hydro-, the rest of the word has a form of root of the second element plus the suffic -ic or -ous

Question 19

What is the second rule in naming acids

Answer 19

The second word is alway acid

Question 20

How do you name a covalent compounds

Answer 20

1.look at the formula, does the compound form an acid aqueous solution
2. No- use normal covalent compound naming system

Yes- Name as an acid.
is there a oxygen present in compound?
No- hydro+root of second element+-ic then acid
Yes- Root of oxyanion + -ic
(If anion ends in -ate or -ous
If the anion ends in -ite the

Question 21

How do you know when an acid ends with -ic or -ous

Answer 21

If the oxyanion ends in -ate then the suffic is then -ic, but if the oxyanion ends in -ite then the suffix is
-ous

Question 22

What does aquous mean?

Answer 22

A solution containing water
