there are seven
The electron configuration of iron is [Ar]3d64s2. The electron shells contain 2, 8, 14 and 2 electrons.
Iron has 26 electrons, so it would have multiple electron clouds corresponding to different energy levels and orbitals. These electron clouds would be distributed in multiple shells around the nucleus according to the principles of quantum mechanics.
Magnesium has three electron shells. The electron configuration is 2,8,2
Bromine has 4 electron shells.
Polonium has 6 electron shells.
Sodium, i believe has 3 shells.
A sulfur atom has 3 electron shells.
There are 26 electrons in an iron atom. Each neutral iron atom has a total of 26 electrons occupying various energy levels or 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.
