Why is `Na^(+)` cation smaller than the parent atom Na ?

Text Solution

AI Generated Solution

To understand why the `Na^(+)` cation is smaller than the parent atom `Na`, we can break down the explanation into several steps: ### Step 1: Determine the Atomic Number and Electron Configuration - Sodium (Na) has an atomic number of 11, which means it has 11 protons and, in its neutral state, 11 electrons. - The electron configuration of sodium is: \[ 1s^2 \, 2s^2 \, 2p^6 \, 3s^1 \] ...
