Q1. Explain why the ionic radius of an anion is generally larger than that of its parent atom.

  1. Addition of electrons increases electron-electron repulsion, expanding the electron cloud
  2. The nuclear charge increases, pulling electrons closer
  3. The number of protons decreases, reducing attraction
  4. The atom loses electrons, causing the radius to increase

Q2. Consider the ions Na+, Mg2+, and Al3+. Which of the following correctly ranks their ionic radii from largest to smallest?

  1. Na+ > Mg2+ > Al3+
  2. Al3+ > Mg2+ > Na+
  3. Mg2+ > Na+ > Al3+
  4. Na+ > Al3+ > Mg2+

Q3. Consider two elements, X and Y, in the same group of the periodic table where Y is below X. Which statement correctly compares their atomic radii?

  1. Element X has a larger atomic radius than element Y.
  2. Element Y has a larger atomic radius than element X.
  3. Both elements have the same atomic radius.
  4. Atomic radius depends only on the number of protons, so cannot be compared.

Q4. The atomic number of an element is 20. Using the Modern Periodic Law, predict the group and period of this element in the periodic table.

  1. Group 2, Period 4
  2. Group 18, Period 3
  3. Group 1, Period 4
  4. Group 16, Period 4

Q5. Which of the following trends correctly describes the variation of first ionization enthalpy across a period in the modern periodic table?

  1. It decreases from left to right across a period
  2. It remains constant across a period
  3. It generally increases from left to right across a period
  4. It fluctuates randomly with no trend

Q6. Consider the elements magnesium (Mg) and aluminum (Al). Which one has a higher first ionization enthalpy and why?

  1. Mg has higher ionization enthalpy due to completely filled s-orbital
  2. Al has higher ionization enthalpy because it has more protons
  3. Both have the same ionization enthalpy as they are in the same period
  4. Al has lower ionization enthalpy due to electron entering a p-orbital

Q7. Which factor primarily causes the atomic radius to decrease when moving from left to right across a period in the periodic table?

  1. Increase in number of electron shells.
  2. Increase in effective nuclear charge without significant increase in shielding.
  3. Decrease in nuclear charge.
  4. Increase in electron-electron repulsion in the outer shell.

Q8. Given the ionic radii of O2- (140 pm), F- (133 pm), and Na+ (102 pm), which of the following statements is true regarding their sizes?

  1. O2- is smaller than F- due to higher nuclear charge
  2. Na+ is the smallest because it has the highest positive charge
  3. F- is larger than O2- because it has fewer electrons
  4. All ions have the same size because they are isoelectronic

Q9. Consider two elements X and Y where X has atomic number 15 and Y has atomic number 16. According to the Modern Periodic Law, which of the following is true about their chemical properties?

  1. They have completely different chemical properties because their atomic masses differ.
  2. They have similar chemical properties because they are in the same group.
  3. They have different chemical properties because they belong to different groups.
  4. Their chemical properties depend only on their physical states.

Q10. In a hypothetical scenario, if the shielding effect in a period increased significantly while the nuclear charge remained constant, what would be the expected trend in atomic radii across that period?

  1. Atomic radius would increase across the period.
  2. Atomic radius would decrease across the period.
  3. Atomic radius would remain constant across the period.
  4. Atomic radius would first increase then decrease across the period.

Q11. Calculate the energy required to remove 2 moles of electrons from 2 moles of gaseous sodium atoms if the first ionization enthalpy of sodium is 496 kJ/mol.

  1. 496 kJ
  2. 992 kJ
  3. 248 kJ
  4. 1984 kJ

Q12. Which factor primarily causes the decrease in ionization enthalpy down a group in the periodic table?

  1. Increase in nuclear charge
  2. Increase in atomic radius and shielding effect
  3. Decrease in number of electrons
  4. Increase in effective nuclear charge

Q13. Consider two elements, X and Y, where X has a smaller atomic radius but lower ionization enthalpy than Y. Which factor could explain this anomaly?

  1. Higher electron shielding in X
  2. X has a half-filled or fully filled subshell
  3. Y has a higher effective nuclear charge
  4. X has more protons than Y

Q14. Which of the following factors primarily causes the ionization enthalpy to increase across a period in the modern periodic table?

  1. Increase in atomic radius
  2. Increase in effective nuclear charge
  3. Increase in electron shielding
  4. Decrease in nuclear charge

Q15. How did the discovery of atomic number influence the arrangement of elements in the Modern Periodic Table?

  1. It allowed elements to be arranged by increasing atomic mass.
  2. It resolved anomalies in Mendeleev's periodic table by arranging elements by nuclear charge.
  3. It grouped elements based on their melting points.
  4. It led to the classification of elements by their isotopic masses.
