Question

among the given species, A+, A-,A the smallest one in size is​

Answer 1

Answer:

The answer for you to my dear friends

:- A+ > A > -A

Answer 2

Among $A^+, A^- and A$, $A^+$ is smallest one.

Explanation:

• The general concept involved in the identification process atomic number of the element.
• The ions with less number of electrons have small size and number of electrons depends upon the atomic number.
• For example, if we consider the atomic number of  'A' as 8, it has eight electrons and being an element it doesn't possess any charge.
• On the other hand, in case of $A^+$, the element  has lost one electron and thus it has 7 electrons. Thus it posses one electron less than 'A' and is smaller than 'A'.

• In case of $A^-$, the element  has gained one electron and thus it has 9 electrons. Thus it posses one electron more than 'A' and is larger than 'A' and $A^+$.
• Thus the ion $A^+$ has fewer electrons, it is considered as the smallest ion.
