Naming of the compounds

Question 1

Exceptions (elements which can only form one type of ion)

Answer 1

Cd(2+)
Zn(2+)
Al(3+)
Ga(3+)
Ag(+)

Question 2

NH3

Answer 2

Ammonia

Question 3

suffix of ions with least amount of oxygen

Answer 3

-ite

Question 4

suffix of ions with most amount of oxygen

Answer 4

-ate

Question 5

N^3-

Answer 5

Nitride

Question 6

PO3^3-

Answer 6

Phosphite

Question 7

which element is the prefix thio

Answer 7

sulfur (S)

Question 8

Binary compound

Answer 8

made of 2 elements

Question 9

binary ionic compound

Answer 9

metal-nonmetal

Question 10

Binary covalent compound

Answer 10

nonmetal-nonmetal

Question 11

Rules for naming binary ionic compound (Type I)

Answer 11

-cation named first, anion named second;
-A monatomic cation takes its name from the name of the parent element;
-A monatomic anion is named by taking the root of the elementname and adding -ide
-the charges must cancel out
-the metal only forms one type of cation so NO roman numerals to precise charge
(KNOW COMMON MONATOMIC CATIONS AND ANIONS -2.3)

Question 12

Rules for naming binary ionic compound (Type II)

Answer 12

**the metal can form more than one type of ion so mucst precise the charge of the element with a roman numeral
***The exceptions are: Cd, Zn, Al, Ga, Ag
-The ion with higher charge has a name ending in –ic
-the one with lower charge with –ous.
[Example: Fe2+ =ferrous ion, Fe3+ =ferric ion]
-In a metal that can make more than one type of cation, the charge of the metal ion must be determined by balancing the positive and negative charge on the ion compound.

Question 13

Binary Covalent compounds (type III)

Answer 13

• this compound is composed of 2 non-metals that share electrons
• the first element in formula is name 1st using the full element name
• the 2nd element is named as if it were an anion
• prefixes are used to denote the number of atoms present
• prefix mono is never used for naming the 1st element
• *prefixes are only used for this type of compound

Question 14

CH4

Answer 14

methane

Question 15

Acids

Answer 15

• acids are proton donors
  i) if the anion does not contain oxygen, the acid is named with the prefix HYDRO and the suffix -IC
  ii) if the anion contains oxygen and if the anion name ends in -ATE: the suffix -IC is added to the root name
  iii) if the anion contains oxygen and if the anion name ends in -ITE: the suffix -OUS is added to the root name

Question 16

Prefixes

Answer 16

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