boiling and melting point of hydrogen

The melting points and boiling points decrease on moving down the group. However, the decrease in melting points is not as regular as in boiling points..

The melting point and boiling point of boron halides increase with increase in the atomic number of halogen..

All alkali metals are soft and have low melting and boiling points. As alkali metals have only one valence electron per metal atom, the energy binding the atoms in the crystal lattice of the metal is low. Consequently, the metallic bonds in these metals are not very s..

Melting Points and Boiling Points - The melting and boiling points of group 14 elements are much higher as compared to those of group 13 elements. Explanation: It is because the atoms of group 14 can form four covalent bonds with..

The melting and boiling points of group 14 elements are much higher as compared to those of group 13 element..

Metals have high melting and boiling point. Tungsten has the highest melting point where as silver has low boiling point. Sodium and potassium have low melting points..

The melting and boiling points of elements are determined by the inter-atomic or inter-molecular forces between the constituent particles in the lattice and liquid state respectively. It is difficult to predict the variation in melting and boiling ..

The melting and boiling points of covalent compounds are generally low. This is because of the fact that the forces between the molecules are weak and thus are easily overcome at low temperature..

Ionic compounds have high melting and boiling points. A large amount of energy is required to break the crystal lattice, because the ions are held together by strong electrostatic forces of attraction. The variation in melting point depends upon th..

Due to the presence of -C N group in the molecules, they have high dipole moment and consequently possess high melting and boiling points despite lack of hydrogen bondin..
