Melting and boiling points
The melting and boiling point of alkaline Earth metals are characteristically low and do not show regular trends down the group. However these points are higher than the corresponding alkali metals in the same period as atoms of alkaline ..
The melting and boiling point of alkaline Earth metals are characteristically low and do not show regular trends down the group. However these points are higher than the corresponding alkali metals in the same period as atoms of alkaline ..Melting Points and Boiling Points
The melting and boiling points of group 14 elements are much higher as compared to those of group 13 element..
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 each other and, therefore, there are strong b..
2. Melting and boiling points
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..
3. Melting and boiling points
The melting and boiling points of halogens increase with increase in atomic number down the group. Explanation: The forces existing between these molecules are weak Van der Waals forces, which increase down the group. This is also clear from the ch..
Melting and boiling points
The melting and boiling points of alkynes increase with molecular mass. Melting boiling points of some alkynes are, Ethyne/acetylene (CH CH), - 83 o C or 190 K Propyne (CH 3 -C CH), - 27 o C or 246 K 1 - Butane (CH 3 -CH 2 -..
Melting and Boiling Point
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..
Melting and boiling 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 ..
Low melting and boiling points
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..
Boiling points
Ammonia (240 K) has a higher boiling point than phosphine (190 K) and then the boiling point increases down the group because of increase in size. In PH 3 and other hydrides, the intermolecular forces are Van der Waals' forces. These van der W..
