Explanation / Answer

Answer:

=> The size increases as you go down the groups and towards the left of periodic table.

=> So the decreasing order is S-2>Cl->K+>Ca+2.

=> Electrons in the cloud are constantly repelling each other.

=> Since all these atoms have same number of electrons, and different in the number of protons.

=> If protons are more, they strongly pull the electrons towards nuclei, so radius will decrease.

=> Here Ca+2 have more number of protons and S-2 have less.
