1
When did Mendeleev create a new row in his periodic table?
when chemical properties were repeated
when the next element was a nonmetal
when the first atomic mass was doubled
when there were 10 elements in the row
2
What is Mendeleev known for?
discovering Mendelevium
discovering protons
publishing the first periodic table
creating today's atomic model
3
Ionization refers to the process of
losing or gaining protons
turning lithium into fluorine
changing from one period to another
losing or gaining electrons
4
Which of the following are the highly reactive Group 1 metals?
alkali metals
transition metals
alkaline-earth metals
semiconductors
5
Which element is a semiconductor?
uranium
sodium
carbon
silicon
6
Magnesium (Mg) is on the right of sodium (Na) because Mg has
no protons
more protons
fewer protons
no neutrons
7
Mendeleev left gaps in his periodic table because
the table was too small
no known elements fit there
the table was too full
protons belonged there
8
Which of the following has properties of metals and nonmetals?
transition metals
alkali metals
halogens
semiconductors
9
Which of the following are the Group 2 elements that have 2 valence electrons?
alkaline-earth metals
halogens
alkali metals
transition metals
10
How was Mendeleev's periodic table arranged?
by decreasing atomic mass
by decreasing atomic number
by increasing atomic number
by increasing atomic mass
11
As you move from left to right across the periodic table, elements
become more metallic
have a lower atomic weight
become less metallic
have a lower atomic number
12
Which of the following is not true of noble gases?
They belong to Group 18
They exist as single atoms
They are nonmetals
They are highly reactive
13
As you move from up to down in a column of the periodic table, elements have
a lower atomic number
a higher atomic number
fewer protons
a higher group number
14
Each column of the periodic table is
a group
a period
an element
an isotope
15
Which statement about noble gases is correct?
They are highly reactive
They exist as single atoms rather than molecules
They form compounds with very bright colors
They are extremely rare in nature
16
Which statement about alkali metals is correct?
They are extremely nonreactive
They form ions with a 1- charge
They are usually gases
They are located in the left-most column
17
The order of the elements in the periodic table is based on an element's
atomic mass
atomic number
name
chemical symbol
18
The periodic law states that elements that have similar properties appear
to the left of each other
at regular intervals
to the right of each other
at every tenth element
19
In Mendeleev's periodic table, elements in each column had similar
properties
atomic masses
atomic numbers
symbols
20
Element sin an element family have similar
chemical properties
atomic weights
atomic sizes
atomic symbols
21
Which of the following is the group of reactive elements that are poor conductors?
transition metals
alkaline-earth metals
semiconductors
halogens
22
How do you know that potassium, an alkali metal, is highly reactive?
It conducts heat
It has one valence electron
It is a soft and shiny metal
It conducts electricity
23
Which of the following are the metals in groups 3-12 that are somewhat reactive?
alkaline-earth metals
semiconductors
alkali metals
transition metals
24
Elements within the same group have similar properties because they have the same number of
neutrons
protons
valence electrons
ions
25
Group 18 noble gases are relatively inert because
their outermost energy level is missing one electron
they readily form positive ions
their s and p orbitals are filled
they can have either a + or - charge
26
Each element in an element family shares the same
number of valence electrons
average atomic mass
number of protons
atomic number
27
Elements that share properties of metals and nonmetals are
periods
ions
valences
semiconductors
28
When can semiconductors conduct heat and electricity?
under no conditions
under some conditions
under almost all conditions
under all conditions
29
Mendeleev's version of the periodic table placed the elements based on their
chemical symbol
name
atomic mass
atomic number
30
Elements in a family often have a similar
number of total protons
number of total electrons
appearance
atomic mass
