Periodic Table Trends Quiz

What are the four main periodic trends discussed in the video?

• Atomic radius, electronegativity, electron affinity, atomic mass

• Atomic mass, electronegativity, electron affinity, ionization energy

• Atomic radius, electronegativity, electron affinity, ionization energy

• Atomic radius, electronegativity, ionization energy, atomic mass

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

• It decreases

• It fluctuates

• It remains the same

• It increases

Why does atomic radius increase down a group?

• Because the number of protons increases

• Because new electron shells are added

• Because the number of neutrons increases

• Because the atomic mass increases

What is electronegativity?

• The energy released when an atom gains an electron

• The ability of an atom to lose electrons

• The energy required to remove an electron

• The ability of an atom to attract shared electrons

How does electronegativity change across a period?

• It increases

• It remains constant

• It fluctuates

• It decreases

What happens to ionization energy as you move down a group?

• It fluctuates

• It increases

• It remains the same

• It decreases

Why is it easier to remove an electron from sodium than from chlorine?

• Sodium has a larger atomic radius

• Chlorine has a larger atomic radius

• Sodium has more protons

• Chlorine has fewer protons

What is electron affinity?

• The energy released when an atom gains an electron

• The ability of an atom to lose electrons

• The energy required to remove an electron

• The ability of an atom to attract shared electrons

How does electron affinity change across a period?

• It fluctuates

• It becomes more negative

• It becomes less negative

• It remains constant

Why does electron affinity decrease down a group?

• Because the number of neutrons increases

• Because the atomic radius decreases

• Because the atomic radius increases

• Because the number of protons increases
