Identify the correct statements about Boron.
I. It has high melting point.
II. It has high density.
III. It has high electrical conductivity
IV. isotope of it has high ability to absorb neutrons
- A I, II only
- B II, III only
- C III, IV only
- D I, IV only
Answer & Solution
Correct Answer
(D) I, IV only
Step-by-step Solution
Detailed explanation
Due to very strong crystalline lattice, boron has unusually high melting point. Rest of the members are soft metals with low melting point and high electrical conductivity. The density of the boron family elements increases down the group due to increase in mass overcomes the…
