Solution
The behavior of an element is largely determined by the number of valence electrons it has. Valence electrons are the electrons in the outermost shell of an atom and are involved in forming bonds with other atoms.
Potassium (K) is in Group 1 of the periodic table, which means it has one valence electron.
Let's look at the options:
A. Krypton (Kr) is in Group 18, so it has eight valence electrons. B. Francium (Fr) is in Group 1, so it has one valence electron. C. Chromium (Cr) is in Group 6, so it has six valence electrons. D. Strontium (Sr) is in Group 2, so it has two valence electrons.
Based on the number of valence electrons, Francium (Fr) would have the closest behavior to Potassium (K) as they both have one valence electron.
