Answer 1

Сверху вниз в периоду и справа налево в группе

Answer 2

The Order of Chemical Elements by Increasing Atomic Radius

The chemical elements are arranged in order of increasing atomic radius in the periodic table. The atomic radius generally decreases across a period (from left to right) and increases down a group (from top to bottom).

The order of chemical elements by increasing atomic radius is as follows:

1. The atomic radius generally increases down a group and decreases across a period in the periodic table.

2. The atomic radius tends to increase down a group due to the addition of energy levels and the shielding effect of inner electrons.

3. Across a period, the atomic radius tends to decrease due to increasing nuclear charge and the attraction of electrons to the nucleus.

4. The specific order of chemical elements by increasing atomic radius can be observed by analyzing the periodic table and considering the trends in atomic radius across periods and groups.

In summary, the atomic radius of chemical elements increases down a group and decreases across a period in the periodic table.
