• 2000

How many elements are known to mankind in the 1860's?

• 118
• 115

When Mendeleev was working on his table, he realized that every 7th element had similar properties. We now know that it is every 8 elements. Why had Mendeleev not discovered this?

• Mendeleev had not made the connection between protons and atomic numbers
• Elements were researched based on their reactivity, therefore, the Noble Gases had not been discovered.
• Mendeleev's model of the table was wrong and that is why the noble gases are not included
• The noble gases are not stable, so scientists could not work with them.

Why did Mendeleev believe his table was not showing perfect repetition? 

• Some elements simplied had not been discovered yet
• It was never going to work
• There were an odd number of elements
• Because the atomic numbers did not add up

Who is the master of the elements?

• Gleen T. Seaborg
• Neils Bohr
• Mendeleev 
• Lise Meitner

Alkali metals are so reactive that they will have a reaction with the atmosphere if not stored correctly. How do scientist get a hold of alkali metals

• From nature
• The extract them from compounds
• Scientist cannot get a hold of these metals
• They can be found in humans

What kind of metals are good conductors of heat and electricity? 

• Alkali metals
• Alkaline metals
• Metalloids 
• Transition metals

What group on the periodic table is completely nonreactive?

• Alkali
• Noble Gases
