WebRecall that most atoms are stable when their outermost ring has eight electrons. (Some atoms, such as lithium and beryllium, are stable when their outermost ring has two electrons.) A. How many electrons will the lithium atom give up to become stable?… Ans: 1 B. How many electrons does the oxygen atom need to become stable?… Ans: 2 C. WebEach lithium atom has one electron in its valence shell (2s 1) that it donates to oxygen to attain a helium-like configuration (1s 2 ). The valence electrons are shown by drawing dots around the atoms. STEP 2: We will draw eight dots around oxygen (six valence electrons and two gained from lithium). iowa digital heritage death certificates
