There will be three electron shells with 2, 8 and 3 electrons (from 1st to 3rd shell).
Aluminium has three electron shells with 2,8,3 electrons each.
Sodium has a larger atomic radius than aluminum.
Aluminum has 3 electron shells, with the middle shell being the second shell. This second shell is also known as the innermost shell of valence electrons.
Polonium has 6 electron shells.
There are 3 electron shells in Aluminum. The first shell holds 2, the second shell holds 8, and the third shell holds 3. This equals 13, its Atomic Number. http://www.chem4kids.com/files/elements/013_shells.html
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Aluminium has three electron shells with 2,8,3 electrons each.
Sodium has a larger atomic radius than aluminum.
Elements in the same row, or period, of the periodic table fill up the same energy level as you move from left to right. This is because elements in the same period have the same number of electron shells.
Magnesium has three electron shells. The electron configuration is 2,8,2
Aluminum has 3 electron shells, with the middle shell being the second shell. This second shell is also known as the innermost shell of valence electrons.
Sodium, i believe has 3 shells.
Bromine has 4 electron shells.
Samarium has six electron shells.
Polonium has 6 electron shells.
There are 3 electron shells in Aluminum. The first shell holds 2, the second shell holds 8, and the third shell holds 3. This equals 13, its Atomic Number. http://www.chem4kids.com/files/elements/013_shells.html
Chromium has two electrons in the outer most shell.
