the first level holds a maximum of 2 and the outershells hold a maximum of 8.
The largest atom is calcium which has 4 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.
A fluorine atom has 2 electron shells. The first shell can hold up to 2 electrons, and the second shell can hold up to 8 electrons, giving a total of 10 electrons for a fluorine atom.
An atom with 16 electrons would have 3 electron shells. The first shell can hold up to 2 electrons, the second shell can hold up to 8 electrons, and the third shell can hold up to 8 electrons.
Sodium has 3 electron shells. The first shell can hold up to 2 electrons, while the second and third shells can hold up to 8 electrons each. Sodium has 11 electrons in total.
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.
