This element is the most reactive on the periodic table?
What is Fluorine?
300
Name the bigger element Beryllium or Barium?
What is Barium?
400
The original periodic table was corrected by placing it in order of increasing
Atomic Number
400
These two groups increase in reactivity down the group.
What is Alkali and Alkali Earth
400
This group has 4 valence electrons?
What is the Carbon group?
400
This element does not belong in it's group because it's properties are very different than the other metals. The only reason it is in the assigned group is because it has 1 valence electron.
What is Hydrogen?
400
These two words are used to describe metals that can be hammered into thin sheets and drawn into wires
What is malleable AND ductile
500
Mendeleev went to university in Russia. What was his country of origin?
What is Serbia?
500
Explain why the atomic radius changes as it does across a group
The more positive nucleus pulls the electrons more inward.
500
This group is not as reactive as group 1, and has a pH that ranges from 8-14.
What is the Alkali Earth group?
500
This shiny metal, that is highly reactive in water, is found in group one and helps to make up your table salt?
What is Sodium
