The Periodic Table is arranged how?

• By element's discovery

• By Atomic Number

• Alphabetically

• By Physical Properties

What is the difference between Atomic Number and Atomic Mass

• Atomic Number is the number protons and Atomic Mass is the average of isotopes

• Atomic Number is the average of isotopes and Atomic Mass is the number of protons

• Atomic Number is the number of electrons and Atomic Mass is the actual mass of an atom

• Atomic Number is the order of discovery and Atomic Mass is the number of protons

Which side of the Periodic Table is most reactive?

• Left side

• Right side

• Top half

• Bottom half

Of the four atoms below, which two would be in the same Group?

• 1 & 2

• 1 & 4

• 1 & 3
