The element of Sodium in the periodic table has a large atomic radius than magnesium due to less atomic attraction on the last electron.
<h3 /><h3>What is the atomic radius?</h3>
The atomic radii are given as the distance between the last electron in the shell to the center of the nucleus.
In the periodic table, on moving from the left to right there has been a decrease in the atomic radius of the atom with the addition of an electron in the same shell forming an increase in the nuclear attraction faced by the last electron.
Thus, Sodium has a large atomic radius than magnesium due to the presence of a less nuclear attraction over the last electron.
