Question

When an atom forms a positive ion (by losing electrons). Will the radius of an ion change from the radius of an atom? Explain with the example of Sodium atom (Atomic no. 11) and Sodium ion

Answer 1

yes it will..
For example sodium ion... it has three shells. its electonic configuration is 281 ....
as it lose one electron to complete its octet it loses 1 shell too... as a result the radius of its ion is smaller than the atom.. all the positive ions are smaller than their parent atom... Hope it helps.....

Answer 2

Yes , when an atom changes to an ion , it's radius changes !!

Sodium atom loses 1 electron to form a uni positive ion.

The electronic from the outermost shell of the sodium atom is removed - therefore reducing the radius of the atom .
