how does atomic size change from left to right in a period

Hey
Due to increase in number of electrons in a period from left to right the attraction force by the protons in the nucleus increases which contracts the size of atom.
Hope it helps :)

On moving across left to right, the atomic number increases
meaning no of electrons increases also nuclear charge also increases
but since s-shell can hold 2 electrons
and p-shell can hold 6 electrons, they get filled with increase in nuclear charge
increase I'm nuclear charge causes contraction which results in decrease in size
so on moving from left to right, the atonic size decreases
