Six shells.

Atoms are the smallest particle there is and can't be broken down any further. Atoms consist of protons and neutrons in the nucleus and electrons in the electron cloud also known as orbitals and shells. Atoms are the building blocks of everything, they make everything everywhere, dead or alive.
They traded with shells that they found near their tribe.The shells showed signs of wealth.A lot of tribes didn't have shells so they traded.
they made their clothes out of shells and grass like clam shells or other shells in ceremonies headdress with feathers from bird such as owls and woodpeckers.

Scientist use the electron cloud model to represent an atom.In the electron cloud model, an atom has two distinct regions-the nucleus and the electron cloud.
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.
Technetium has five electron shells.
