Six.
Tantalum has 73 electrons. The number of electron orbits in an atom is equal to the number of electron shells, which is determined by the quantum number n. Tantalum's electron configuration is [Xe] 4f14 5d3 6s2, indicating that it has 6 electron orbits.
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.
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.
Nickel has 3 (three) electron shells.
Chromium has two electrons in the outer most shell.
