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 and boiling points
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 each other and, therefore, there are strong binding forces between their at..
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..
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 point and boiling point of boron halides increase with increase in the atomic number of halogen..
The melting point and boiling point of boron halides increase with increase in the atomic number of halogen..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..
3. Melting and boiling points
The melting and boiling points increase with the increase in atomic number as we go down the group. Explanation: When we move down the group, the molecular size increases. As a result, the magnitude of the van der Waals forces also increases with increase in atomic nu..
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 change of state from f..
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 Waals' forc..

Tutor was excellent, asnwered the question rapidly and provided the information I needed to understand the problem.
This Tutor Vista is GREAT! loved this session, it helped me heaps.
VERY HELPFULL! I understand through the formulas given to read the equation when worked great job
Tutor are so organized and neat with their teachings. She set up everything that made the problems more understandable by showing them in such a simple manner, I feel I could really learn from them and pertain it to my class! :)
Looking for More Help!
