WebFeb 27, 2024 · Boiling point trend in group 13. Since atomic mass increases down the group, the van der Waal's forces should also operate to a greater extent, thereby making it difficult to change the phase of the substance. Hence, boiling point should increase down the group from boron to thallium. But in my book, the answer given is that the forces of ... WebAll Group 1 elements: (a) are soft, solid, shiny metals at room temperature and pressure that are good conductors of heat and electricity. (b) have 1 valence electron (1 electron in the highest energy level) (c) are very reactive. (d) form cations with a charge of +1 ( M +) when they combine with non-metals in an ionic compound.
WebApr 4, 2013 · You have to know that elements with high lattice energy has high melting and boilng point.And since lattice energy is inversely related with radius of atoms it increases down a group and hence the melting point increases. ... The melting and boiling point decreases down the group up to group 14 (not including transition metals), but the trend ... WebAll the elements of the group exist in a polyatomic state. First, Nitrogen is gas, but as you move down, there is a significant increase in the metallic character of the elements. Nitrogen and Phosphorus are non-metals, Arsenic …

WebAug 28, 2024 · In groups 1, 2, 13 and 14, the melting and boiling point decreases down the group with a few exceptions. In group 15 the melting/boiling point increases up to Arsenic and then started decreasing. In groups 16, 17 and 18 it increases down the group, but with few exceptions.
WebJan 24, 2024 · Melting and Boiling Points The melting points of group \ (13\) elements do not follow a regular pattern, as elements from groups \ (1\) and \ (2\) do. This is most likely due to the peculiar crystal structures of B and Ga. Actually, as one moves down the group from B to Ga, the melting points decrease sharply and then increase from Ga to Tl.
