As you move from to on the periodic table, the atomic radius of the atoms increase. a) top, bottom correct answer b) bottom, top c) left, right d) top left, bottom right

The correct option is: A) top, bottom

Explanation:

In the periodic table, chemical elements are arranged or organized in the increasing order of atomic number (Z). It consists of 18 vertical columns, known as the groups and 7 horizontal rows, known as the periods.

As we move horizontally across the period, i.e. from the left to the right of the periodic table, the atomic radius generally decreases.

Whereas, when going vertically down the group, i.e. from the top to the bottom of the periodic table, the number of shells increases. Therefore, the atomic radius also increases.
