Anionic Radius

Assertion : ...

Question

Assertion : $N a^{+}$ and $A l^{3 +}$ are isoelectronic but the magnitude of ionic radius of $A l^{3 +}$ is less than that of $N a^{+}$ . Reason: The magnitude of effective nuclear charge of the outershell electrons in $A l^{3 +}$ is greater than that in $N a^{+}$ .

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
The magnitude of effective nuclear charge of the outershell electrons in $A l^{3 +}$ is greater than that in $N a^{+}$ .
Thus, $N a^{+}$ and $A l^{3 +}$ are isoelectronic but the magnitude of ionic radius of $A l^{3 +}$ is less than that of $N a^{+}$ .
Thus, both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
