#Explanation#The Lewis dot notation is a way of representing the valence electrons in an atom. Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms. In this case, the Lewis dot notation is showing the transfer of an electron from one atom to another. This is a characteristic of ionic bonding, where one atom (usually a metal) loses an electron and another atom (usually a non-metal) gains that electron. Potassium (K) is a metal with one valence electron, while Chlorine (Cl) is a non-metal with seven valence electrons. In order for both atoms to achieve a stable electron configuration, Potassium will lose its one valence electron to Chlorine. This results in Potassium having a +1 charge (since it has lost a negatively charged electron) and Chlorine having a -1 charge (since it has gained a negatively charged electron).#Answer#The correct answer is "K loses one electron to Cl".
