Question

write scientific reason:- atomic radius goes on decreasing while going from left to right in a period​

Answer 1

Answer:

atomic radius decreases as we move from right to left

Explanation:

in a period from left to right the number of valence electrons in the same shell increases due to which the effective nuclear charge increases and therefore atomic size decreases as we move from left to right in a period

Answer 2

Answer:

atomic radius goes on decreasing while going from left to right in a period because of an atomic number of the elements increase which means the number of protons and electrons in the atom increase.

atomic size gradually decreases from left to right across a period of elements this is because, with in the a period or family of elements, all electrons are added to the same shell,

the valence electrons are held closer towards the nucleus of the atom as a result, the atomic radius decreases.
