The following ions contain the same number of electrons. rank them in order of decreasing ionic radii.? a. na+b. mg 2+c. al 3+d. o 2-e. n 3-f. f -

N3- > O2- > F- > Na+ > Mg2+ > Al3+

Explanation:

The ionic radio can simply be defined as the distance from the center of the nucleus to the electron in the outermost shell.

It should be noticed that all these ions belong to elements in group 3 of the periodic table.

It must be noted that anions I.e negative ions are generally bigger than anions.

Hence, it is expected that the negative ions are bigger. The arrangement goes thus:

N3- > O2- > F- > Na+ > Mg2+ > Al3+

solute : a solute is a substance that is dissolved in another substance is known as a solvent. it is mixed with a special mixture know as homogeneous mixture.

solvent: a solvent is a substance that dissolved a solute, which results in a solution is known as solvent.
