Forming an Ion
This electron exchange results in an electrostatic attraction between the two atoms called an ionic bond. An atom that loses one or more valence electrons to become a positively charged ion is known as a cation, while an atom that gains electrons and becomes negatively charged is known as an anion.
Energy is released when
a. valence electrons are removed from an atom.
b. valence electrons are gained by an atom.
c. a positive ion forms.d. two of the aboveAN ENERGY IS RELEASED WHEN VALENCE ELECTRONS ARE REMOVED FROM AN ATOM AND VALENCE ELECTRONS ARE GAINED BY AN ATOM
