(General)
Properties
100
This scientist created the periodic table based on mass.
Who is Dmitri Mendeleev?
100
This type of element touches the "stair step".
What are Metalloids?
100
Families 1A and 2A.
What are the Alkali Metals and the Alkali Earth Metals?
100
Horizontally arranged on the periodic table.
What are Periods?
100
Hard and shiny, three or less valence electrons and good conductors of electricity.
What are Metals?
200
This scientist created today's periodic table based on atomic number.
Who is Henri Moseley?
200
Elements to the left side of the periodic table.
What are metals?
200
Families 3A and 4A.
What are the Boron and Carbon groups?
200
Vertically arranged on the Periodic Table.
What are Families?
200
Gases or dull, brittle solids. 5 or more valence electrons, poor conductors of heat.
What are nonmetals?
300
This scientist discovered two elements and investigated what is now radioactivity. This scientist also won a Nobel Peace Prize in 1911.
Who is Marie Curie?
300
Elements to the right of the periodic table.
What are nonmetals?
300
Families 5A and 6A.
What are the Nitrogen and Oxygen groups?
300
States that when elements when arranged in order of increasing atomic number their physical and chemical properties show a periodical pattern.
What is the periodic law?
300
Appearance will vary. 3-7 valence electrons, conduct better than nonmetals, but worse than metals.
What are Metalloids?
400
This scientist created a similar version of the Periodic Table as Dmitri Mendeleev.
Who is Lothar Myer?
400
The general middle area of the periodic table.
What are transition metals?
400
Families 7A and 8A.
What are the Halogens and the Noble Gases?
400
The elements are arranged in order (from lowest to highest) _______.
What is atomic number?
400
Neither an alkali metal or a halogen. (Doesn't fall into a specific category.)
What is the Halogen element?
500
These two scientists are most known for their work on the periodic table.
Who are Mendeleev and Moseley?
500
The two rows below the periodic table.
What are transition metals?
500
Families in the same period all have the same _______.
Number of valence shells.
500
A map of the ding blocks of matter.
What is the Periodic Table?
500
React with water easy, form a +1 ion, found in nature combined with other elements, good conductors of heat and electricity.
What are Alkali Metals? (1A)
