-
ionic bond-a nonmetal and a metal or two metals
-
covalent bond-two nonmetals
-
ionic bond-two nonmetals or two metals
-

Pregunta 5
Pregunta
An acid is a chemical substance that neutralizes alkalis, dissolves some metals, and turns litmus red; typically corrosive. it has a PH less than 7
Respuesta
- True
- False
Pregunta 6
Pregunta
What are the two types of acids?
Respuesta
-
binary acid and oxyacid
-
tertiary acid and ionic acid
Pregunta 7
Pregunta
What is the difference between polyatomic ions and monatomic ions?
Respuesta
-
Polyatomic ions are made up of two or more atoms bonded together that acts as a single unit with a net charge Monatomic ions are formed from only one atom
-
There isn't a difference
-
Monatomic ions have more atoms than polyatomic ions
Pregunta 8
Pregunta
An ion is an atom or bonded group of atoms with a positive or negative charge
Respuesta
- True
- False
Pregunta 9
Pregunta
A chemical bond doesn't hold atoms together
Respuesta
- True
- False
Pregunta 10
Pregunta
What is the difference between a binary compound and a tertiary compound
Respuesta
-
a binary compound has two different elements while a tertiary compound has three
-
there isn't a difference
-
the number of atoms
Pregunta 11
Pregunta
Check the steps involved in naming binary acids
Respuesta
-
The first word has the prefix hydro-
-
The rest of the first word consists of a form of the root of the second element with the prefix -ic
-
the second word is acid
-
identify the oxyanion present
-
it the elements name ends with -ate replace it with -ic
Pregunta 12
Pregunta
The following steps are the steps for naming oxyacids:
1. Identify the oxyanion present
2. The first word of an oxyacid;s name consists of the root of the oxyanion present and the prefix per- or hypo- if it is part of the name and a suffix
3. If the oxyanion's name ends with -ate replace it with -ic, if it ends with -ite replace it with the suffix -ous
4. The second word of the name is always acid
Respuesta
- True
- False
Pregunta 13
Pregunta
Which of these is correct when naming binary ionic compounds?
Respuesta
-
it must be a metal and a nonmetal or two metals the total charge of the compound must equal zero use the CDR method use the stock system
-
the total charge of the compound doesn't matter the CDR method s only useful sometimes the rules apply to any compound
-
there are no rules or precautions
-
the stock system isn't relevant
Pregunta 14
Pregunta
The stock system is a type of nomenclature that uses roman numerals to indicate charge of a transition metal
Respuesta
- True
- False
Pregunta 15
Pregunta
Check all of the binary ionic naming rules
Respuesta
-
name the metal/cation by its elemental name
-
name the nonmetal/anion by its elemental name with the ending -ide
-
determine the charge of the metal and indicate it with a roman numeral
Pregunta 16
Pregunta
What are the binary ionic naming rules with transitional metals?
Respuesta
-
1. name the metal/cation by its elemental name 2. determine the charge of the metal and indicate it with a roman numeral in parenthesis 3, name the nonmetal/anion by its elemental name with the suffix -ide
-
1. name the metal/cation by its elemental name 2. name the nonmetal/anion by its elemental name with the suffix -ide
-
1. name the metal/cation by its elemental name 2. name the polyatomic ion
Pregunta 17
Pregunta
The rules following are the rules for naming a polyatomic ion:
1. Name the metal/cation by its elemental name- if a transitional metal is present, use a roman numeral
2. name the polyatomic ion
Respuesta
- True
- False
Pregunta 18
Pregunta
Covalent compounds are made of two metals
Respuesta
- True
- False
Pregunta 19
Pregunta
What is unique about covalent bonds?
Respuesta
-
they have prefixes
-
they use roman numerals
-
they don't use suffixes
Pregunta 20
Pregunta
In covalent bonds, a prefix is used on the first element if there are 2+ atoms of that element present
Respuesta
- True
- False
Pregunta 21
Pregunta
In covalent bonds, a prefix on the second element is not essential
Respuesta
- True
- False
Pregunta 22
Pregunta
You can reduce in covalent compounds
Respuesta
- True
- False
Pregunta 23
Pregunta
Check all the rules that apply to naming covalent compounds
Respuesta
-
The first element in the formula is always named first, using the entire element name
-
The second element in a formula is named using its root and the suffix -ide
-
Prefixes are used to indicate the number of atoms of each element that are present in the compound
-
The rules that apply to ionic bonds apply to naming covalent bonds
-
