Periodic Table Quiz

_______________ developed the first periodic table and arranged the elements in order of increasing atomic mass.

• Stevie Wonder
• Sasha Vujacic
• Dmitri Mendeleev
• James Mosely

Which property did Mendeleev use to order his periodic table?

• Shielding effect
• Eletronegitivity
• Atomic Weight
• Metallic Character

What was Dmitri Mendeleev's greatest contribution to the history of the periodic table?

• He arranged all of the known elements by their atomic number
• He realised that there was a pattern of reactivity which repeated every 8 elements
• He predicted the existence (and properties) of new elements
• He identified the "law of triads" which became the groups

Mendeleev classified elements based on not only atomic mass but what else?                                                   

• reactivity
• boiling points
• physical properties only 
•  chemical & physical properties

• halogen
• noble gas

Which is an alkaline earth metal?

• Calcium
• Rubidium
