Periodic Trends Review

How does the atomic radius change as you move across a period?

• It decreases
• It is unpredictable
• It remains constant
• It increases

Which of the following factors influences the atomic radius?

• Number of valence electrons
• Number of energy levels
• Number of neutrons
• Number of protons

Which of the following is a periodic trend?

• The boiling point of an element
• The number of valence electrons in an element
• The mass of an element
• The atomic number of an element

Which of the following factors does NOT influence periodic trends?

• Atomic radius
• Ionization energy
• Electronegativity
• Atomic mass

What is the relationship between atomic structure and periodic trends?

• Periodic trends are only affected by the mass of an atom
• Atomic structure has no influence on periodic trends
• Periodic trends are solely determined by the number of protons in an atom
• Periodic trends are influenced by the arrangement of electrons in energy levels

Which of the following factors influences the electronegativity?

• Number of neutrons
• Number of protons
• Number of valence electrons
• Number of energy levels

How does the number of valence electrons affect periodic trends?

• Elements with more valence electrons tend to have higher ionization energies
• Elements with more valence electrons tend to have lower electronegativities
• It has no effect on periodic trends
• Elements with more valence electrons tend to have larger atomic radii
