Which of the following statements is correct about the differences of physical properties of Boron and other elements of this group?
Correct answer: D. All of these
- A. It is a non-metal and other elements are metals
- B. It is a semi-conductor and other elements are conductors
- C. Its ionization energy is higher than other elements
- D. All of these
Explanation
The correct answer is Option D: 'All of these.' Boron stands out in Group III-A as a non-metal, a semiconductor, and having a higher ionization energy compared to other elements in the group. Options A, B, and C focus on individual properties, while Option D encompasses all the correct statements about Boron's unique physical properties.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
