It's predicted that this element will be shown to have seven. Please see the link.
Technetium has five electron shells.
Magnesium has three electron shells. The electron configuration is 2,8,2
There can only be 1 outer energy level.
A bismuth atom has 6 electron shells.
Phosphorus in is 3rd period. So it has 3 electron shells.
Berkelium has seven electron shells.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
see what period it is in on the periodic table it is in period 6, so therefore there are 6 electron shells or energy levels
