Answer:

correct order is

O2>–Na>Mg>Al3

Step-by-step explanation:

Ionic radius is the radius of a monatomic ion in an ionic crystal structure.

  • Al3 has the smallest ionic radius of the given ions .
  • O2 has the largest ionic radius of the given ions.

hence the correct decreasing order is as follows:

O2>–Na>Mg>Al3
