प्रश्न
Give the trends in atomic size on moving across the period left to right.

उत्तर
Atomic size decreases from left to right as the Atomic Number increases by one at each stage, with one proton added to the nucleus and one electron added to the valence shell. As nuclear attraction rises, the size of the atom decreases.
