The electron configurations of the noble gases are extremely stable. The octet rule states that, in chemical reactions, elements gain or lose electrons to achieve a noble gas configuration. This stable configuration is called an octet because it consists of 8 valence electrons (s2 p 6 ), 2 from the outermost s orbital and 6 from the outermost p orbital. Oxygen has the electron configuration 1s2 2s2 2p 4 . When oxygen reacts to form ionic compounds, it completes its octet by gaining two electrons from the element it reacts with. These two electrons add to the p orbital of oxygen, giving it the electron configuration (1s2 2s2 2p 6 ) of neon.

About the flashcard:

This flashcard is meant to be used for studying, quizzing and learning new information. Many scouting web questions are common questions that are typically seen in the classroom, for homework or on quizzes and tests. Flashcards vary depending on the topic, questions and age group. The cards are meant to be seen as a digital flashcard as they appear double sided, or rather hide the answer giving you the opportunity to think about the question at hand and answer it in your head or on a sheet before revealing the correct answer to yourself or studying partner. Some questions will include multiple choice options to show you the options involved and other questions will just have the questions and corrects answers. Simply reveal the answer when you are ready to check your work. Absolutely no cheating is acceptable.
