wk 13 Valence

what is not true regarding the octet rule?

• states that every atom wants to have eight valence electrons in its outermost electron shell
• atoms combine to form molecules they generally each lose, gain, or share valence electrons until they attain or share eight
• to obtain the same electronic configuration as a noble gas.
• goal is to obtain valence similar to group I
