The addition of electron shells results in more shielding of electrons from the nucleus.
Polonium has 6 electron shells.
Chromium has two electrons in the outer most shell.

A sulfur atom has 3 electron shells.
No, iodine has four electron shells, marked as "K", "L", "M", and "N". The number of electron shells is determined by the electron configuration of an element.
Elements in the same row, or period, of the periodic table fill up the same energy level as you move from left to right. This is because elements in the same period have the same number of electron shells.
Magnesium has three electron shells. The electron configuration is 2,8,2
Sodium, i believe has 3 shells.
Bromine has 4 electron shells.
Polonium has 6 electron shells.
Samarium has six electron shells.
According to me the atomic size of an atom increases or decreses with the change in the number of shells. As atomic size is defined as the distance between the nucleus and valence shell of an atom. So, the addition of an electron does not effect the atomic size. As we can see in the periodic table that while moving along a group the number of electrons increases along with increase in no. of shells, while the atomic size tends to be increase with addition of shells and neglecting the addition of electrons. Same is the case while moving along a period. Atomic size decreases while the attraction between increased nuleus charge increases . Thus the size of the atom decreases.
Nickel has 3 (three) electron shells.
Chromium has two electrons in the outer most shell.
A sulfur atom has 3 electron shells.
No, iodine has four electron shells, marked as "K", "L", "M", and "N". The number of electron shells is determined by the electron configuration of an element.
