FINAL EXAM CHM 151 RIO SOLADO M.SCHAAB LATEST UPDATE GRADED A+ What is the difference between an ionic bond and a covalent bond? An ionic bond is formed when one atom transfers electrons to another atom, creating ions that attract each other. A covalent bond is formed when two atoms share electrons. How do you determine the number of valence electrons in an element? The number of valence electrons can be determined by looking at the group number of the element in the periodic t...
