Based on the electron configuration of sulfur, S, a sulfur atom will gain or lose how many valence electrons when bonding with lithium?
With a metal, sulfur acts as an oxidizing agent, i.e. it formally accepts electrons.............
And if we wanted to (which we do) we could split this up into half equations:
And in terms of electron configuration, sulfur gains 2 valence electrons to give 8 valence electrons.
And lithium loses 1 valence electron to give a
