  1. State whether element C would be a metal or a non-metal. Why?
  2. Which is the more active element, A or C? Why?
  3. Which type of ion (cation or anion) will be formed by the element C? Why?
✓

Answer

  1. A is non metal.
  2. Stament c is less reactive that A.
  3. C is much smaller that the size of the B.
A will be form anion. hope this right answer derived from the table so the student can simply check out right ideas from it.
