Question

the radius of Na+ cation is less than that of Na atom . Give reason ​

Answer 1

Answer:

The atomic radius of Na⁺ is less than that of Na,because due to the loss of 1e ⁻,the inter electronic repulsion by the electrons in the inner shell decreases. As the interelectronic repulsion decreases, the attraction between the nuclei and the outermost electron increases,leading to the decrease in the atomic size.

Answer 2

Answer:

because it losses an electron to become stable so it's atomic size is less
