Sagot :

ciqarz

Answer:

Ne

Explanation:

Neon is the element with the most stable outer electron configuration because it has eight valence electrons that fill the outer shell. Eight electrons in the outer shell is the most stable arrangement of electrons. Neon is also a noble gas which means that due to it already having a complete outer shell, it doesn't lose, gain, or share electrons. Therefore, it is stable.

Hope that helps.
