Why does lithium have a smaller atomic radius then potassium?

because the second ionisation means removing the second electron from the potassium atom. Potassium only has one electrin in its outer most shell so the second electron would be in another electron shell which is closer to the nucleus meaning there is a stronger attraction to that electron because of the protons in the nucleus which are positive and attrct the negative electrons so more energy is needed to remove the second electron
