Understanding the Periodic Table and Periodic Trends

What are the vertical columns in the periodic table called?

• Rows

• Blocks

• Groups

• Periods

Which side of the periodic table generally contains non-metals?

• Left

• Right

• Top

• Bottom

As you move from left to right across a period, what happens to the atomic radius?

• It fluctuates

• It remains the same

• It decreases

• It increases

What is ionization energy?

• Energy required to remove an electron

• Energy required to add an electron

• Energy released when an electron is removed

• Energy released when an electron is added

How does ionization energy change as you move up a group in the periodic table?

• It fluctuates

• It increases

• It decreases

• It remains constant

What does a negative electron affinity indicate?

• The atom wants to lose an electron

• Energy is required to add an electron

• Energy is released when an electron is added

• The atom does not want an electron

Which element is likely to have a very negative electron affinity?

• Fluorine

• Rubidium

• Strontium

• Helium

What is electronegativity?

• The size of an atom

• The energy required to remove an electron

• The attraction of an atom for electrons in a bond

• The energy released when an electron is added

Which element has the highest electronegativity?

• Nitrogen

• Carbon

• Oxygen

• Fluorine

What is the correct order of elements based on decreasing electronegativity?

• C, N, O, F, S, Br, H

• F, O, N, C, Br, S, H

• Br, S, H, C, N, O, F

• H, S, Br, C, N, O, F
