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).

The LiO2 molecule is a misnomer: the bonds between lithium and oxygen are highly ionic, with almost complete electron-transfer. The force constant between the two oxygen atoms matches the constants measured for the superoxide anion (O2 ) in other contexts. The bond length for the O-O bond was determined to be 1.34 Å. Using a simple crystal structure optimization, the Li-O bond was calculated to be approximately 2.10 Å.
