Int the most stable electron configuration, the outer electron shell has ____ electons?

Question

(this is a question for my science)

Answer 1

The most stable configuration is when the entire shell is full (noble gas configuration).

Next best is when a specific orbital (s, p, d, f, etc.) is completely full, even if the shell is not complete.

Next best after that is when a specific orbital is exactly half full.

All atoms would like to attain electron configurations like noble gases, i.e., have completed outer shells. Atoms can form stable electron configurations like noble gases by losing electrons, gaining electrons and sharing electrons.

For a stable configuration each atom must fill its outer energy level. In the case of noble gases there will be eight electrons in the valence (outer most) shell (with the exception of He which has two electrons).

Atoms that have 1, 2 or 3 electrons in their outer levels will tend to lose them in interactions with atoms that have 5, 6 or 7 electrons in their outer levels. Atoms that have 5, 6 or 7 electrons in their outer levels will tend to gain electrons from atoms with 1, 2 or 3 electrons in their outer levels. Atoms that have 4 electrons in the outer most energy level will tend neither to totally lose nor totally gain electrons during interactions and thus they tend to share electrons.

Answer 2

In the most stable electron configuration, the outer electron shell has 8 electrons. For example, xenon is a stable atom and it contains 8 electrons in its outermost shell.

Answer 3

8.

it's always 8.

when an element has to either gain or lose elements the result is always 8.

so say Boron (Idk if this is really Boron's # jus an ex.) has 7 electrons, it will gain one so it balances out.

say Lithium has 3 it will gain 5 to balance out.

-good luck

hope this helped! : )
