What makes an atom stable?

A. An outer electron shell that has 2 electrons in it
B. A full outer shell of electrons


Sagot :

Final answer:

Atoms are stable when they have a full outer shell of electrons, typically eight electrons. Elements bond with each other to achieve this stability by sharing or transferring electrons.


Explanation:

Atoms achieve stability by having a full outer shell of electrons. The outer shell is considered full when it contains eight electrons, except for hydrogen and helium which are stable with two electrons. Elements bond with other elements to achieve a full outer shell through sharing or transferring electrons.
