Bond Notes

Ionic Bond * bond formed between oppositely charged ions because of electrostatic forces of attraction. *<Tab/>example: sodium + chlorine ----> sodium chloride Ionic compound * a compound composed of ions. * Metal atoms lose electrons to form positive ions, called cations, which are smaller than the original atom. The loss of an energy level with electrons, plus the excess positive charge draws the remaining electrons toward the nucleus and causes the electron cloud …showed first 75 words of 1051 total…
