No it doesn't... Aluminum has 3 extra electrons in the outer shell
The chemical nature of the substance. The rare earths all have a similar 'outer shell', and differ only in their 'inner shells', hence the similarity of many of their properties.
The outer shell (N=4) of the copper element has 2 electrons.
Berkelium has 97 electrons, which means it has 7 electron shells.
Hydrogen has only one valence electrons.
The nonmetals usually gain or share however many electrons they need to complete their outer shell. Metals tend to lose the electrons in their outer shell, so that one of the inner shells essentially becomes the outer shell.
There is 3
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
Beryllium has one outer electron shell with two electrons.
There are 3 electrons in the outer shell of aluminum.
The Inner Reaches of Outer Space has 160 pages.

The calcium atom has 2 outer shell electrons. It's configuration is: [Ar] 4s2 it also has 2 inner shell electrons

Darmstadtium has seven electron shells around the nucleus.
None, the outer core sits directly on top of the inner core.
Florine have only 2 shells namely 1s and 2s is is inner and 2s is outer shell I there is any question related to chemistry then ask me....
Mendelevium has seven electron shells.
