the no. of electron shells in an atom varies for every element in the Periodic Table, depending on its no. of electrons in the atom. the no. of shells of an atom of an element ca be derived through the period of the periodic table. elements in the 1st period has only 1 shell and so forth.
Magnesium has three electron shells. The electron configuration is 2,8,2
A bismuth atom has 6 electron shells.
Phosphorus in is 3rd period. So it has 3 electron shells.
Curium has seven electron shells.
Yttrium has five electron shells.
Bromine has 4 electron shells.
Polonium has 6 electron shells.
Magnesium has three electron shells. The electron configuration is 2,8,2
Sodium, i believe has 3 shells.
A sulfur atom has 3 electron shells.
Uranium has 92 electrons, which means it has 7 electron shells.
The correct number of electron clouds or shells sodium has is 3.
A bismuth atom has 6 electron shells.
Phosphorus in is 3rd period. So it has 3 electron shells.
Chromium has two electrons in the outer most shell.
Nickel has 3 (three) electron shells.
Curium has seven electron shells.
