Periodic Table Concepts and Properties

What does each box on the periodic table represent?

• A molecule

• An atom

• An element

• A compound

What does the atomic number of an element indicate?

• The number of neutrons

• The number of electrons

• The number of protons

• The atomic mass

How are elements primarily arranged on the periodic table?

• Alphabetically by name

• By increasing atomic mass

• By increasing atomic number

• By color-coding

Which of the following is NOT typically found as a primary piece of information in a single element box on the periodic table?

• Atomic number

• Atomic mass

• Number of neutrons

• Element symbol

What are the vertical columns on the periodic table called?

• Periods

• Rows

• Groups

• Series

What do elements in the same group on the periodic table typically share?

• Similar atomic mass

• Similar number of electron shells

• Similar chemical characteristics

• Similar atomic radius

What happens to the atomic radius as you move down through the periods on the periodic table?

• It decreases

• It increases

• It remains the same

• It varies unpredictably

What happens to the ionization energy as you move from left to right across the groups on the periodic table?

• It decreases

• It increases

• It remains the same

• It varies unpredictably
