उत्तर
Going across a period left to right, atomic size Decrease.
Atomic size gradually decreases from left to right across a period of elements. ... This means that the nucleus attracts the electrons more strongly, pulling the atom's shell closer to the nucleus. The valence electrons are held closer towards the nucleus of the atom. As a result, the atomic radius decreases
