Question

Name the properties of the elements which,

increase in going from top to bottom in a group.

Answer 1

Atomic size - Increases in going from top to bottom in a group

1. The properties of the elements that increase from top to bottom are the Size of the atom and atomic number.
2. As we move down a group the electrons are added to the new shell and so the atomic radius in turn size of the atom also increases.
3. Thus we go down a group from top to bottom, the atomic size increases gradually,
