Why do the melting points of group 2 elements not show regular trends?
Atoms have large ionic radii
Atoms of elements have smaller size
Atoms adopt different crystal structures
Atoms have high nuclear charges
Melting points of group 2 elements show irregular trends becuase atoms adopt different crystal structures.
In case of noble gases the general trend in the melting points and boiling points, down the group, is
Which of the following group elements exhibits high melting and boiling points?
