Periodic Trends Challenge


Froggy Jumps Periodic Trends ChallengeOnline version Test your understanding of periodic trends and the modern table. by Amari 1 What is the primary purpose of the modern periodic table? a To group rocks by mineral content b To rank elements by color and shape c To organize elements by properties and atomic structure 2 Which property increases across a period due to rising nuclear charge? a Atomic radius b Ionization energy c Electron affinity 3 What happens to atomic radius across a period (left to right)? a Remains the same b It increases steadily c It generally decreases 4 Why do noble gases have low electronegativity values? a They are highly reactive b They have full valence shells c They have high ionization energy 5 Which trend explains why alkali metals lose electrons easily? a Large atomic radius b Low first ionization energy c High electron affinity 6 What is the term for the size of an ion compared to its neutral atom? a Covalent radius b Nuclear radius c Ionic radius 7 Why are anions generally larger than their neutral atoms? a Increased nuclear charge b Added electrons increase repulsion c Decreased electron shielding 8 What drives periodic law and repeated properties across periods? a Random element placement b Periodic repetition of electron configurations c Arbitrary grouping 9 Which factor primarily influences ionization energy across a period? a Increasing nuclear charge with electron shielding b Increasing atomic mass c Decreasing nucleus size 10 Which group has the highest electronegativity on the table? a Halogens b Alkali metals c Noble gases 11 What happens to ionic radius when forming cations? a It decreases b It increases c It stays the same 12 Which statement best describes electron shielding across a period? a Shielding decreases to zero b Shielding changes little; nuclear charge rises c Shielding dominates; radius grows 13 Which trend explains why metals become more reactive toward the left? a Higher electronegativity inward b Lower ionization energies inward c Smaller atomic radii inward 14 What is electronegativity a measure of? a Its melting point b An atom’s ability to attract electrons c Its mass 15 Which element property is most responsible for periodic trends? a Boiling point b Electron configuration c Color 16 Which factor causes noble gases to bond only rarely? a High electron affinity b Stable electron configurations c Low nuclear charge 17 What is the Moseley update to the periodic table primarily about? a Order by nuclear charge (Z) b Color coding by group c Alphabetical order 18 Which trend describes ionization energy across a period? a Stays constant b Generally decreases c Generally increases 19 What happens to the metallic character as you move across a period? a It oscillates randomly b It increases c It decreases 20 Which group is known for high reactivity and low ionization energy? a Transition metals b Alkali metals c Noble gases 21 Why do nonmetals tend to gain electrons? a To complete their valence shell b To lower ionization energy c To increase mass 22 What is the term for the energy required to remove the first electron? a Atomic radius b Electron affinity c First ionization energy 23 Which property is most related to the distance to the valence shell? a Ionization energy b Electronegativity c Atomic radius
