Question

explain the change of atomic size in periodic table​

Answer 1

Answer:

The size of an atom is defined by the edge of its orbital. However, orbital boundaries are fuzzy and in fact are variable under different conditions. In order to standardize the measurement of atomic radii, the distance between the nuclei of two identical atoms bonded together is measured. The atomic radius is defined as one-half the distance between the nuclei of identical atoms that are bonded together

Answer 2

Answer:

the atomic size decreases along period

increases down the group

Explanation:

becauase as we move along period the effective nuclear charge increases which pull valance electron toward nucleas hence size decreases

as we move down group a new shell is added

and valance shell start to move away from nucleus hence size increases

hope it helps
