Question

Arrange the following in the order of their increasing size :
Cl-, S²-,Ca²+,Ar​

Answer 1

Answer:

Hii friend,

Here is your answer...

The increasing order of size will be

Ca2+ < Ar < Cl- < S²-

Explanation:

In general the size of ions will be in the order of

cation< Neutral < Anion.

This is because in cations due to lack of elctrons effective nuclear charge by the nucleus towards the valence electrons will be maximum and hence it's size gets decreases.

:- The correct size in increasing order will be

Ca2+.< Ar < Cl- < S²-.

Hope this helps you a little!!!
