100
This man found a pattern among the elements.
Who is Dmitri Mendeleev?
100
Elements with similar properties are arranged in these.
What are groups?
100
Elements in the rows appear periodic, meaning this.
What is a repeating pattern?
100
Elements that are unreactive.
What are noble gases?
100
One property of nonmetals.
What is dull, poor conductors?
200
Henry Moseley changed the arrangement of the periodic table by putting the elements in order of this.
What is increasing atomic number?
200
The alkaline metals are in this group.
What is group 2?
200
The most reactive metals.
What are alkali metals?
200
The reactivity of alkali metals compared to alkaline metals.
What is more reactive than alkaline metals?
200
Most elements on the periodic table are in this class.
What are metals?
300
Rows of the periodic table.
What are periods?
300
Elements in group 18 have this many electrons in their outer shell.
What is 8 electrons?
300
Elements in groups 3-12 are called this.
What are transition metals?
300
Elements with 3 electrons in the outer level are part of this group.
What is 13 or boron group?
300
This element is a metalloid.
What is boron, silicon, germanium, arsenic, antimony, or tellurium?
400
The columns of the periodic table.
What groups or families?
400
Chlorine, Fluorine, Bromine and Iodine are all part of this group.
What is group 17 or halogen group?
400
The number of protons represented by this.
What is the atomic number?
400
These groups contain metalloids.
What are groups 13-16?
400
This states that chemical and physical properties of elements are periodic functions of atomic number.
What is the periodic law?
500
These are the three classes of elements.
What are metals, nonmetals and metalloids?
500
An element that is a very reactive gas is most likely a member of this group.
What is group 17 or halogen?
500
Understanding the pattern of the properties of the elements allows you to predict what?
What is the properties of missing or undiscovered elements?
500
Most chemical symbols are determined by this.
What is the first letter of the element?
500
These elements are considered semiconductors.
What are metalloids?
