how does the size of a potassium atom compare with the size of a sodium atom
give a reason for your answer

potassium (K) has a larger average atomic radius (220 pm)than sodium (Na) does (180 pm). The potassium atom has an extra electron shell compared to the sodium atom, which means its valence electrons are further from the nucleus, giving potassium a larger atomic radius.

The atomic size of sodium is smaller than the atomic size of potassium.

Let us remember that the atomic size increases down the group as more shell are added to an atom. We should also recall the sodium is ahead of potassium in group one.

This simply means that the atomic size of sodium is smaller than the atomic size of potassium. This is in keeping with the trends of atomic radius down the group.
