the no. of electron shells in an atom varies for every element in the Periodic Table, depending on its no. of electrons in the atom. the no. of shells of an atom of an element ca be derived through the period of the periodic table. elements in the 1st period has only 1 shell and so forth.
Depending on the number of electrons there can be from 1 to 7 electron shells!
An electron does not have "electron shells" at all; these are characteristic of atoms, not electrons. No electron can occupy more than one shell of an atom unless the atom is excited.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Phosphorus in is 3rd period. So it has 3 electron shells.
Magnesium has three electron shells. The electron configuration is 2,8,2
Curium has seven electron shells.
Yttrium has five electron shells.
Selenium has four electron shells.
Plutonium has seven electron shells.
Magnesium has 3 electron shells. The electron configuration is : 2,8,1
The correct number of electron clouds or shells sodium has is 3.
Phosphorus in is 3rd period. So it has 3 electron shells.
Magnesium has three electron shells. The electron configuration is 2,8,2
They have the same number of shells (or energy levels).
Hassium has seven electron shells.
Polonium has 6 electron shells.
Uranium has seven electron shells.
Technetium has five electron shells.
Curium has seven electron shells.
Yttrium has five electron shells.
