Question

which is smallest in size c4- n3- o2- f-

Answer 1

Answer:

F- is the smallest

Explanation:

the order of anion is as follows:

F- < O2- < N3- < C4-

the size of anion increases as the magnitude of charge increases.

anions are formed when the atom gains electron.

as they gain more electron their size increases more.

to compare the size between cation anion and the original atom it is as follow:

cation < original atom < anion

I HOPE THIS IS HELPFUL
