The Noble Gases, group 18 (or VIIIa) of the Periodic Table, have complete outermost shells. They are helium, neon, argon, krypton, xenon, and radon.
An element with a complete valence electron shell is a noble gas. Noble gases have a full outer electron shell, making them stable and non-reactive. Examples include helium, neon, and argon.
The key to "happiness" for an atom is a full outer electron shell. (The outer electron shell is called the valence shell.) There are two conditions that cause a shell not to be full. Either it has only an electron or two (or three) in the outer electron shell or it's short an electron or two in that outer shell. The direct answer to the question is that if an element is chemically active, its outer electron shell is incomplete or is not full.
The element with 6 outer shell electrons is carbon. Carbon has 4 electrons in its outer shell and 2 electrons in the shell before that, totaling 6 outer shell electrons.
Magnesium. The complete electron configuration is: 1s2 2s2 2p6 3s2 The complete electron arrangement is: 2e, 8e, 2e
Elements in Group 1 of the periodic table have one electron in their outer shell, while elements in Group 2 have two electrons in their outer shell. This configuration makes these elements more stable and likely to form ions with a positive charge by losing these outer electrons to achieve a full outer shell.

There are different electrons in the outer shell of each element.
This is an ionic bond.
Its outer electron shell is complete, with 2 electrons. Therefore it does not readily bond with other elements.
A complete octet of electrons (8) in the outer-most, or valence, shell.
No, it doesn't have a complete octet. Phosphorous is in group 5A, meaning it has 5 valence electrons (5 electrons on its outest shell).

The outer shell (N=4) of the copper element has 2 electrons.

Elements in Group 1 of the periodic table have one electron in their outer shell, while elements in Group 2 have two electrons in their outer shell.

Boron has 3 electrons in the outer shell and 2 electrons in the inner.
