Answers
what |is |the |relationship |between |radius |and |energy |of |ion |- |ion |- |CORRECT |ANSWER✔✔-as |
radius |goes |down |energy |of |ion |- |ion |goes |up
which |elements |can |hydrogen |bond |- |CORRECT |ANSWER✔✔-HFON
polaribility |- |CORRECT |ANSWER✔✔-relative |ease |that |the |electrons |have |in |a |molecule |can |be
