Which information cannot be deduced from the fact that an element has low I.E?

Correct answer: D. It belongs to the p-block

  • A. It is a metal
  • B. It forms positive ions
  • C. It may form an ionic bond
  • D. It belongs to the p-block

Explanation

The correct answer is D: It belongs to the p-block. Elements with low ionization energy are usually found in the s-block of the periodic table, such as alkali and alkaline earth metals, which lose electrons easily. In contrast, p-block elements generally have higher ionization energies as they are more likely to gain electrons rather than lose them. Therefore, the information that an element has low ionization energy cannot be used to deduce that it belongs to the p-block.Option A is incorrect because metals generally have low ionization energies. Option B is incorrect because elements with low ionization energy tend to form positive ions by losing electrons easily. Option C is incorrect because elements with low ionization energy can participate in forming ionic bonds with non-metals.

About Chemical Bonding

Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
