[03.04]when one atom of potassium (k) combines with one atom of fluorine (f), an ionic bond forms, resulting in potassium fluoride (kf). which of the following describes the arrangement of valence electrons in a bond between k and f?

the valence electrons are shared equally between k and f.
the valence electrons spend more time around the atom of k.
the valence electrons spend more time around the atom of f.
the valence electrons are given up by the k and gained by the f.
