Question

Compare the size of potassium atom and potassium cation.

Answer 1

Answer:

+1 charge means that potassium atom has lost 1 electron. Therefore, a potassium ion has a smaller radius since it has less electrons. P.S. The number of protons gives the identity of the element. Therefore, an atom or an ion of potassium must always have the same number of protons (19).
