K is larger

Assuming your talking about chemistry and potassium, K. Because K1+ means that that there is one additional electron in the orbital. An electron is 'negative' weight so K would be larger.

K has the electron formula -1s2,2s2 2p6,3s2 3p6 3d10,4s1
K1+ has the electron formula-1s2, 2s2 2p6,3s2 3p6 3d10
i.e. one electron and also one shell is removed when K gives one electron to form K1+ and that why the former (K) is larger in size.

my dear kavita, potassium does not have d orbitals. please recheck your electron configs.
potassium atom has a specific atomic radius, which is largely determined by the number of electron shells the atom has. by removing one atom from K (which is group I by the way), you are effectively vacating the entire outer shell (since there's only one electron in the outermost shell for group I's). therefore the K+ ion must be smaller than the K atom.
