Question

what are the variations in the physical properties
Answer in brief

Answer 1

The physical properties of elements depend in part on their valence electron configurations. As this configuration remains the same within a group, physical properties tend to remain somewhat consistent.

The most notable within-group changes in physical properties occur in Groups 13, 14, and 15, where the elements at the top are non-metallic, while the elements at the bottom are metals

Answer 2

Physical properties of matter can be observed and tested. They include properties such as color, length, volume, odor, and density. These properties are extensive if they depend on the amount of the substance being used or intensive if they do not depend on the amount of substance being used
