Organizing The Elements
Test Description: This review covers material where Mendeleev was organizing the known elements of his time.
Instructions: Answer all questions to get your test result.
1) The first elements to be identified were mainly:
A
liquids
B
plasma
C
gases
D
metals
2) As the number of known elements grew, so did the need to organize them into groups based on their:
A
symbols
B
properties
C
number of neutrons
D
number of quarks
3) Mendeleev organized his periodic table of elements into rows based on increasing:
A
weight
B
temperature
C
density
D
mass
4) As Mendeleev organized his periodic table, he made sure that elements with similar properties were in the same:
A
diameter
B
row
C
column
D
level
5) An arrangement of elements into rows of increasing mass where elements with similar properties end up in the same column is called a:
A
mass table
B
table of properties
C
table of periods
D
periodic table
6) Why did Mendeleev not make a complete table of elements?
A
elements were not alphabetical
B
he had to use to many columns
C
not all elements had been discovered
D
erratic mass numbers
7) In the modern periodic table, elements are arranged according to increasing number of:
A
electrons
B
neutrons
C
protons
D
quarks
8) From energy level to energy level the number of elements varies because the number of available orbits:
A
decreases
B
has reached capacity
C
stays contant
D
increases
9) Each column in the periodic table is called a group where each element has similar:
A
density formulas
B
proton placements
C
isotopes
D
electron configurations
10) An elements chemical properties are determined by its:
A
electron configuration
B
number of neutrons
C
isotope arrangement
D
proton placements
