TEST REVIEW S Valence Electrons TEST REVIEW SHEET 2017
... NOTE: If an element has <4 valence electrons it will give them away during an ionic bond and become a positive ion. If >4, it will take them and become a negative ion For the most part…. metals will give away their valence electrons and nonmetals will take enough valence electrons to fill their oute ...
