NEETChemistryClassification of Elements and Periodicity in Properties

Among the elements B, Al, C, and Si, which element has the most metallic character? Justify your answer.

Options

  1. AB; because it has the highest number of valence electrons.
  2. BAl; because it has the lowest ionisation energy.
  3. CC; because it has the highest electronegativity.
  4. DSi; because it has a larger atomic size and tends to lose electrons easily.

Correct answer

B. Al; because it has the lowest ionisation energy.

Step-by-step solution

Correct Option is : (B) Al; because it has the lowest ionisation energy.
