oxide ion is O2-
atomic number is Z=8 irrespective of oxygen is neutral or under ionic form. Z is also the number of proton
Under neutral form O has 8 electrons . Under O2- , there are two electrons more so O2- has 10 electrons . with configuration 1s22s2sp6

Big-bang theory see my link (theory was progressively builded)

Steady state theory (1948)Hoyle, Gold and Bondi (see link)
