The properties or physical constants which are lower for hydrogen than that of deuterium are:
Open in App
Solution
The correct options are
A Latent heat of fusion
B Activation energy
C Boiling point
The isotopes of any element will have the same number of valence electrons or valency,resulting in identical chemical properties.
The isotopes' physical properties are different mainly due to the neutron number variation, present in the nucleus. Properties such as melting point,Activation energy,,Latent heat of fusion boiling point, density etc., which depend upon the atomic mass should be different for different isotopes because the isotopes of an element have different masses.
The properties or physical constants which are lower for hydrogen than that of deuterium are Boiling point,Latent heat of fusion and Activation energy.
But abundance is more for hydrogen than deuterium.
Hence options B,C & D are correct.
