Lithium is a metal with an oxidation number of 1+ and oxygen is a nonmetal with an oxidation number of 2-. which chemical formula represents the compound formed by these two elements? a) li2o b) li3o c) lio d) lio2

A)

Explanation: In order to form a neutral compound the charges must be balanced. Thus in order to neutralize the 2- charge on oxygen atom, two atoms of lithium with +1 charge must combine.

Lithium is a metal with one valence electron to form .

Oxygen is a non metal with 6 valence electrons to give

They combine to form .

answer; i believe the correct answer is (c) /// is a homogeneous mixture of gaseous substance nitrogen,oxygen and smaller amounts of other substancesmixtures can be either ( homogeneous or heterogeneous)plz check first good luck

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.
