I. Boron has a high melting point of 2352K. So, statement I is correct.
II. Boron has a low density of 2.37gcm−3. So, statement II is incorrect.
III. Boron has low electrical conductivity at low temperature.
So, statement III is incorrect.
IV. B−10 isotope is a neutron absorber due to the high neutron cross-section of isotope ‌10B. So, statement IV is also correct.
Hence, statements I and IV are correct.
