Boiling point order of 13 & 14 group in a periodic table??
Answers
answer
Boiling and melting points of group 13 elements
B, Al, Ga, In, Tl are the elements of group 13 elements. Melting and boiling points decrease on moving down the group. However, the decrease in melting point is not as regular as in boiler points. Ga has very low melting point(303K).
Group 13 elements Melting Point (K) Boiling Point (K)
Boron 2453 3923
Aluminium 933 2740
Gallium 300 2676
Indium 430 2353
Thallium 576 1730
Melting and boiling points of group 14 elements
The atoms of this group form covalent bonds with each other and therefore, there are strong binding forces between their atoms in both solid and liquid states.
Melting and boiling points of group 14 elements are much higher than group 13 elements.
When moving down the group, the melting and boiling points decreases.

Carbon 4100 4827
Silicon 1420 3280
Germanium 945 2850
Tin 232 2623
Lead 327 1751
