How would the size of the K atom compare to the size of K 1+?

Understand the Problem

The question is asking for a comparison of the atomic size of the potassium (K) atom with its ionized form, K 1+. It implies an understanding of atomic structure and ionization effects on atomic size.

Answer

K+ is smaller than K.

The final answer is that the K+ ion is smaller in size compared to the K atom.

Answer for screen readers

The final answer is that the K+ ion is smaller in size compared to the K atom.

More Information

A K atom becomes a K+ ion by losing its outermost electron, which reduces its electron cloud size and increases the effective nuclear charge, pulling the electrons closer to the nucleus.

Tips

A common mistake is to think that the loss of an electron might increase the size due to repulsion effects among remaining electrons.
