Dear Nisha chaudary,
concept of atomic size goes like this
1) say there are same electrons and protons for some atom. if u remove one electron from that the protons are higher than electrons. thatswhy we put + sign on the element for removing electron. when we removed the electron the protons are more so they attract electrons more strongly. so the atomic size will reduce
2) if we take an electron the electrons increases. for that we put an - (negative sign) on that element. in this case elements are more so and protons are low. less protons attracts less so the atomic size will increase.
3) in this question u need to calculate the protons and electrons for each atom and then u have to decide which one is bigger.
ex: k+ has 19 protons and 18 electrons and cl- has 17 protons and 18 electrons.
u can se that the atomic size is greater when electrons are grater than protons therefore the cl- has greater atomic size that k+
