The false statement regarding periodic table is to be identified. Concept Introduction: The total distance that exists between the nucleus and the valence shell electrons of an atom is known to be the atomic size of that atom. According to the periodic table, the atomic size increases while going down the group and decreases while moving from left to right in the period. The energy that is needed to eliminate an electron from a neutral atom is known as ionization energy. According to the periodic table, the ionization energy of the elements increases while moving left to right in the period due to decrease in the atomic size. On the other hand, the ionization energy of the elements decreases while going down the group due to increase in the atomic size of the elements.

Solution Summary: The author explains that the atomic size of an atom increases while going down the group and decreases while moving from left to right in the period.
Definition Definition Number of protons in the nucleus of an atom. It uniquely identifies an element, as the number of protons determines the element's properties. The periodic table of elements is arranged based on increasing atomic numbers, allowing scientists to easily locate and study elements.

Interpretation:
The false statement regarding periodic table is to be identified.
Concept Introduction:
The total distance that exists between the nucleus and the valence shell electrons of an atom is known to be the atomic size of that atom. According to the periodic table, the atomic size increases while going down the group and decreases while moving from left to right in the period.
The energy that is needed to eliminate an electron from a neutral atom is known as ionization energy.
According to the periodic table, the ionization energy of the elements increases while moving left to right in the period due to decrease in the atomic size. On the other hand, the ionization energy of the elements decreases while going down the group due to increase in the atomic size of the elements.
